Explanation:

The sentence above is using the superlative form correctly.

All the other 3 statements on the other hand, are using the superlative form incorrectly, because they are attaching the world "most" to short adjectives, and "most" can only be added to long adjectives like "delicious", or "beautiful".

Explanation:

Sundiata Keïta was Mansa de Malí between 1235 and 1255. The Epopeya de Sundiata, told from generation to generation by the Mandinga people, is based on their life.

a history of Sundiata Keita is essentially known for the epic told from generation to generation until our days through the djelis (bards).

The Maghan Naré Kon Fatta was a Mandingo king, faama of the small kingdom of Niani in western Africa. One day, he was visited by a fortune teller who predicted that an ugly woman would one day give him a son who would become a great king. Naré Konaté was already married to Sassouma Berté and had a son named Dankaran Touman. So, some years later, when two hunters from the country of Do introduced him to an ugly, humpbacked woman named Sogolon Kédjou, he remembered the prediction and married her. His second wife gave birth to a son who was baptized Sundiata Keita. He was a child crippled throughout his childhood, unable to stand.

After the death of the father in 1218, Dankaran Toumani Keita, the first son took power despite the desire of the late king to respect the prediction. Sundiata and her mother (who had given birth to two daughters and adopted the son of Naré Kon Fatta's third wife) were objects of contempt on the part of the new king and his mother. After an affront to his mother, seven-year-old Sundjata managed to stand up: legend has it that he miraculously regained the use of his legs when he touched the royal staff. But the wrath of Sassouma Berté and Dankaran Touman drove Sundjata, her mother and sisters into exile in the kingdom of Mema.

Soumaoro Kanté, the king sosso, attacked the kingdom Manden and Dankaran Touman Keita, fearing for his life, had to flee. According to tradition, Soumaoro carried out a dozen expeditions in the course of which he massacred eleven of the sons of the previous maghan, Naré Kon Fatta, except Soundiata Keita.

The commanders went to look for Sundiata Keita in her exile. The young prince became very popular among the Mandingas, as they expected him to one day end the Sulay invaders. This increasing popularity disturbed Soumaoro, whom the sorcerers had predicted: Your victor will be born in Mali. To escape his revenge, Sundjata took refuge in the house of a neighboring sovereign, his friend, who reigned in Wagadou, in the south of the country. There, he waited for the favorable moment to release his reign.

Sundjata trained himself from a young age in the technique of archery. For years he lived with the idea of avenging the massacre of his family. One day, an emissary announces the revolt of the orders against Soumaro Kanté.

He gathered warriors, conquered Fouta-Djalon and launched the attack against the Sosso kingdom. To know the secret of the invulnerability of Soumaoro Kanté, he sends his sister Djegue who, according to tradition, knows the secret that only an arrow carrying the spur of a white rooster can kill the king of Sosso. So did Sundiata with the help of the magicians who were at his service.

Regrouped the armies of the different small kingdoms in struggle against the sosso, and managed to defeat the army of Soumaoro Kanté, was 1235 in Kirina. Soumaro Kanté disappeared behind a Kulikoró mountain.
