(c)

Upto ordinary heights the change in the distance of a projectile from the centre of the earth is negligible compared to the radius of the earth. Hence, projectile moves under a nearly uniform gravitation force and its path is parabolic. But for projectile going to great height, the gravitational force decreases in inverse proportion to the square of the distance of the projectile from the centre of the earth. Under such a variable force the path of projectile is elliptical.

Both Assertion and Reason are true and reason is the correct explanation of Assertion.
