Answer Key : (c) -

(c)

Let be mass of planet and that of sun, the radius between the two. Let the planet be moving with velocity then

Gravitational force = centripetal force

Hence, larger the distance, smaller the orbital velocity. At point distance from sun is maximum, hence orbital velocity is lowest. At point distance from sun is minimum, hence orbital velocity is maximum.
