What happens if the input frequency is kept lower than the frequency at which the gain is zero?

(a) Circuit act like a perfect integrator

(b) Circuit act like an inverting amplifier

(c) Circuit act like a voltage follower

(d) Circuit act like a differentiator

I got this question during an internship interview.

I need to ask this question from Integrator topic in section Operational Amplifier Applications of Linear Integrated Circuits

Right choice is (b) Circuit act like an inverting amplifier

Simplify with an easy explanation: If the input frequency is lower that the lower frequency limit of the integrator (i.e. when gain = 0), there will be no integration results and the circuit act like a simple inverting amplifier.
