Answer: (a) Frequency response

Explanation: Frequency response refers to the variation of the output signal of a system or device as a function of frequency. It describes how the amplitude and phase of the output signal change when the system is exposed to different input frequencies. This is a critical characteristic in systems like air flow measurement in engines, where response to varying frequencies (such as rapid changes in air flow) needs to be understood and analyzed.
