Correct answer: B. Gravity of the planetary body

  • A. Pressure of the planetary body
  • B. Gravity of the planetary body
  • C. Charge of the planetary body
  • D. Heat of the planetary body

Explanation

Gravity pulls atmospheric gases toward a planet and prevents most of them from escaping into space. Pressure, charge, and heat can affect the atmosphere, but they do not hold it in place as gravity does.
