A planet revolving in elliptical orbit has
I. a constant velocity of revolution
II. has the least velocity when it is nearest to the sun
III. its areal velocity is directly proportional to its velocity.
IV. areal velocity is inversely proportional to its velocity.
V. to follow a trajectory such that the areal velocity is constant.
Choose the correct answer from the options given below.

Correct option: D
Only V
Option D (Only V) is correct because Kepler's Second Law states that a planet's areal velocity remains constant throughout its orbit.
