Increasing jitter buffer size smoothens jitter but at the cost of introducing additional delay.

Excessive jitter buffering can lead to perceptible audio or video lag, impacting user experience.

C: Therefore, the undesired effect is increased transport delay, potentially leading to quality issues if the buffer size is too large.

Why other options are incorrect:

A and D: Jitter buffering does not improve jitter itself; it masks it at the expense of delay.

B: Jitter compensation doesn ' t increase jitter, but delay.
