Identify the graph which correctly represents the variation of capacitive reactance ($X_C$) with frequency ($f$)

The correct answer is Option (3) → 

Capacitive reactance is given by:

$X_C = \frac{1}{2 \pi f C}$

Hence, $X_C$ is inversely proportional to frequency ($f$).

As frequency increases, capacitive reactance decreases.

Variation: $X_C \propto \frac{1}{f}$
