Answer: Latency
Option A (Availability) is incorrect because it pertains to the uptime of the database, not the response time. Option B (Correctness) is incorrect as it measures whether the right data was returned, not how quickly. Option C (Latency) is correct because it directly measures how long a request takes to complete, which is crucial for ensuring timely responses in a banking application. Option D (Throughput) is incorrect as it measures the number of requests handled per time, not the speed of individual responses.
