Question 14

Ceres is a dwarf planet located in the asteroid belt, which is between Mars and Jupiter. The inner planets are Mercury, Venus, Earth, Mars; outer planets are beyond the asteroid belt; Kuiper Belt is beyond Neptune. So the correct option is the one with "asteroid belt".

Venus is known as the hottest planet due to its thick carbon dioxide atmosphere (greenhouse effect), has a rotation period of 243 Earth days, and is called the "Morning Star" (also "Evening Star"). Mercury is close to the Sun but Venus is hotter due to atmosphere; Earth and Mars don't match these characteristics.

So the correct answer is the fourth option: asteroid belt. But since the user's options are presented as O (radio buttons) with labels: inner planets, Kuiper Belt, outer planets, asteroid belt. So the correct one is the one with "asteroid belt".
