Hexagon A’B’C’D’E’F’ is the image of the hexagon ABCDEF

Option (c) is the correct answer.

Explanation:

Bronsted-Lowry stated that acids are the species which donate a proton whereas bases are the species which accept a proton.

Also, a strong acid results in the formation of a weak conjugate base and a weak acid results in the formation of a strong conjugate base.

Similarly a strong base results in the formation of a weak conjugate acid and a weak base results in the formation of a strong conjugate base.

The reaction for hydrofluoric acid and acetic acid is as follows.

Thus, hydrofluoric acid being a strong acid gives a weak conjugate base whereas acetic acid being a weak acid gives strong conjugate base .

Hence, the conjugate base of hydrofluoric acid is weaker than that of acetic acid.
