Explanation:

Question 3

Amongst the planets in the solar system, Mercury has the smallest size (in terms of diameter and mass when compared to others like Venus, Mars, Jupiter).

Venus has a thick atmosphere that traps heat, making it the hottest planet even though Mercury is closer to the Sun. Its atmospheric composition and greenhouse effect lead to higher temperatures than Mercury.

Saturn is well - known for its rings, and these rings are primarily composed of ice particles (along with rock and dust). Venus has no rings, Jupiter's rings are not as prominent or ice - dominated as Saturn's, and Neptune's rings are different in composition and less well - known for being ice - ring dominated compared to Saturn.

Answer:

A. Mercury
