42. What is one of the four inner planets?

Answer: B

Explanation:

Venus is one of the four inner planets.

Venus is classified as one of the four inner planets, which include Mercury, Venus, Earth, and Mars. These planets are characterized by their rocky surfaces and are located closer to the Sun compared to the outer planets.

A) Jupiter

Jupiter is not one of the inner planets; it is classified as a gas giant and is the largest planet in our solar system. It is located far beyond the asteroid belt and is part of the outer planets, which include Jupiter, Saturn, Uranus, and Neptune.

B) Venus

Venus is indeed one of the four inner planets. It is the second planet from the Sun and is often referred to as Earth's "sister planet" due to its similar size and composition. Its rocky surface and proximity to the Sun place it firmly within the category of inner planets.

C) Uranus

Uranus is categorized as an outer planet and is classified as an ice giant. It is located much further from the Sun than the inner planets and is not part of the group that includes Mercury, Venus, Earth, and Mars.

D) Neptune

Neptune is also an outer planet, specifically an ice giant, and is located at a significant distance from the Sun. Like Uranus, it is not considered one of the inner planets due to its position beyond the asteroid belt.

Conclusion

Venus is definitively the correct answer as it is one of the four inner planets, distinguished by its rocky structure and proximity to the Sun. In contrast, Jupiter, Uranus, and Neptune are all outer planets, which do not fit the criteria established by the question.
