Answer

Brief Explanations:

Weight is the force due to gravity, calculated by $F = mg$ (where $m$ is mass and $g$ is gravitational - acceleration). The mass of an object is constant. Gravitational acceleration depends on the mass of the planet and the distance from its center. Mars has a smaller mass than Earth, resulting in a lower gravitational acceleration on Mars. So, the rover weighs less on Mars.

Answer:

B. The mass of Mars is less than the mass of Earth.
