Correct answer: D
Increasing the time quantum reduces context switch overhead, which lowers turnaround time. However, it also increases waiting times for short processes arriving after long ones. Since the net effect depends on specific process burst times and arrival patterns, the average turnaround time varies irregularly rather than following a fixed trend.
