According to "Astrophysicist Chronicles Battle over Pluto," Dr. Tyson decide to exclude Pluto from the exhibits of planets, because it displays the characteristics of an icy body rather than a planet.

Explanation:

Astrophysicist Chronicles Battle over Pluto is a story of one of our solar system planet ‘Pluto.’ When Will Galmot visited the American Museum of Natural History, he noticed that it included hundreds of planet except Pluto. So he sent a letter to the museum authorities as to why Pluto isn’t included.

In 2006 when Dr. Tyson excluded the planet Pluto and labeled it as ‘dwarf planet’ he was criticized my many and he gave a justification by stating that, Pluto is no more than just a icy body, we cannot label Pluto a planet. If Pluto takes the place of earth, from the rays coming from sun will would dry up that ice and what will remain will just be a piece of its tail.’

the answer is "it is one of the trickiest doors to open". i took the test and that was the correct answer.
