Solution

The correct option is (C) S
As we know that the range is maximum when the angle of projection is $45^{\circ}$ .
As the angle of projection increases the range decreases.
When the angle of projection is very far from $45^{\circ}$ then the range will be minimum. So at $60^{\circ}$ the range will be minimum.
