Two identical charged spheres suspended from a common distance d(d<<1) apart because of their mutual repulsion. The charged begin to leak from both the spheres at a constant rate. As a result, the spheres approach each other with a velocity v. Then v varies as a function of the distance x between the spheres, as

A
v∝x21​
B
v∝x
C
v∝x−21​
D
v∝x−1
