Question

according to \astrophysicist chronicles battle over pluto,\ why did dr. tyson decide to exclude pluto from the exhibits of planets?
a. because it displays the characteristics of an icy body rather than a planet
b. because the international astronomical union said it was not a planet
c. because it was too small to be noticeable among the other exhibits
d. because he didnt have enough room left in the solar system exhibit

Explanation:

The text "Astrophysicist Chronicles Battle over Pluto" states that Dr. Tyson excluded Pluto because it has the traits of an icy Kuiper Belt object, not a traditional planet. The IAU's reclassification happened after his exhibit decision, and size/space issues are not the cited reasons.

Answer:

A. Because it displays the characteristics of an icy body rather than a planet
