Answer: B

Explanation:

Transaction nesting allows performance testers to measure both individual activities within a transaction and the aggregate performance of the entire transaction. This is beneficial because it helps identify specific areas where performance issues may be occurring. By understanding both the granular and overall performance, testers can better pinpoint bottlenecks and optimize the system. This aligns with the ISTQB principles of comprehensive performance measurement and analysis to ensure system reliability and efficiency.
