Answer: A

Explanation:

• Disk fragmentation (I) can lead to slower data retrieval times as the disk has to work harder to read fragmented files.

• File repository growth (III) increases the amount of data that must be managed and retrieved, which can slow down response times.

• Memory leaks (IV) gradually consume available memory, leading to slower system performance as the available memory for processing tasks decreases.

Network latency (II) and inadequate database design (V) are also potential causes of performance degradation, but in this context, options I, III, and IV are the most directly related to the gradual degradation of response times over time. This understanding is supported by common performance testing practices outlined in ISTQB materials.
