B. Your mass is too low.
C. Mars is a larger planet than Earth.
D. Mars is a long distance away.

Answers

The correct answer is option D. Mars is a long distance away.

So, the gravitational force exhibited by the Mars is not experienced by us due to the large distance.

The correct response for why you can't feel the force of attraction between you and Mars is because D. Mars is a long distance away, and thus why there is no gravitation attraction between you and Mars.
