    Answer:c-The gravitational effect when spacecraft flies close to the asteriod

    Explanation:

    Gravitational effect on the spacecraft gives an estimate that how big is the asteroid by experiencing its gravitational pull.

    The amount of extra thrust required to maintain the trajectory of the spacecraft during its motion hints at the scientist about the size of the asteroid.

    Gravitational pull is directly proportional to the mass of object so greater the mass, greater will be the pull.
