Solution

The correct option is B
When a pendulum oscillates in air, its total mechanical energy decreases continuously in overcoming resistance due to air. Thus, the total mechanical energy of the pendulum decreases exponentially with time.

The variation of $E v s t$ is correctly represented by curve (c) time as shown.

Final Answer: (𝑐)
