What does the Bode plot of a system represent, where H( ω) is the system's frequency response?

Correct option is A

​$$\text{A Bode plot consists of two plots:} \\[6pt]\text{1. Magnitude plot } \rightarrow |H(\omega)| \text{ (usually in dB) vs. frequency (log scale)} \\[4pt]\text{2. Phase plot } \rightarrow \angle H(\omega) \text{ vs. frequency (log scale)} \\[8pt]\text{It graphically represents how the system’s frequency response varies with frequency.}$$​​
