Answer 2

Explanation:

In the solar system, the sun will engulf Mercury and Venus, and may devour Earth, as well. A red giant star is a dying star in the last stages of stellar evolution. In only a few billion years, our own sun will turn into a red giant star, expand and engulf the inner planets, possibly even Earth.
