d) depends on the value of the circuit components
The maximum voltage gain of a passive low pass filter depends on the values of the circuit components used, such as resistors, capacitors, and inductors. These values determine the cutoff frequency, which is the frequency at which the filter starts attenuating the input signal. The gain of the filter at frequencies below the cutoff frequency will be close to 1 (0dB) and will gradually decrease as the frequency increases. Thus, the maximum voltage gain will be determined by the specific values of the circuit components chosen for the low pass filter.
