The correct answer is:
B

The time period of a simple pendulum of length is given by the formula:
Squaring both sides, we get:
Rearranging the equation to find the relationship between and :
Let and . The equation becomes:
where is a constant.
This is the equation of a rectangular hyperbola in the first quadrant.
As increases, decreases non-linearly, approaching the axes asymptotically.
Comparing this with the given plots, option correctly represents a hyperbolic relationship between and .
