Explanation

Interrupt latency is defined as the time interval between the moment an interrupt signal is generated by a hardware device and the moment the processor begins executing the first instruction of the corresponding Interrupt Service Routine (ISR). Other options describe the execution time itself or context saving, which are components of the total handling time but not the latency.
