Consider the following statements in case of terrestrial planets: I. Mercury, Venus, Earth and Mars are terrestrial planets having low densities as compared to other planets. II. They lie between the Sun and the belt of asteroids. III. Their lower gravity can hold the escaping gases. Which of the statements given above is/are correct?

Options

  1. AI and II
  2. BII and III
  3. CI and III
  4. DII only

Correct answer

B. II and III
