Question:

a. Mars has no atmosphere.

b. Mercury has no atmosphere.

c. Mars and Venus have similar atmospheres.

d. Earth and Venus have similar atmospheres.

e. Venus's atmosphere is thick and contains clouds of sulfuric acid.

Answer:

c. Mars and Venus have similar atmospheres.

e. Venus's atmosphere is thick and contains clouds of sulfuric acid.

Explanation:

The composition of the atmosphere in Mars is about 95% carbon dioxide and 2.6% nitrogen and Argon 1.9% while the atmosphere of Venus also have similar composition consisting of 96.5% carbon dioxide, 3.5% nitrogen and traces of argon.

The atmosphere is much thicker on the planet Venus, such that the 3.5% nitrogen content is equivalent to four times the nitrogen gas present here on Earth's atmosphere. Also the atmosphere on Venus supports sulfuric acid clouds, making the surface of Venus obscure from viewing.
