Why are footballs generally spherical in shape?

The correct option is To ensure uniform motion.

Explanation:

A spherical shape has complete rotational symmetry. When a spherical object such as a standard football is kicked or thrown, it rolls or moves predictably in any direction. Because all points on the surface of a sphere are at an equal distance from its center, the gravitational and drag forces act symmetrically upon it during motion.

This aerodynamic and structural symmetry ensures smooth rolling, consistent bouncing, and uniform motion in all directions, making the trajectory of the ball predictable and fair during gameplay.
