How to achieve maximum CMRR in the given circuit?

(a) R1 = RF

(b) RF = R3|| RC+ RB and R1= R2

(c) R1= R2 and RF= R3+ RC

(d) None of the mentioned

The question was posed to me in a dream while sleeping

I need to ask this question from Input Offset Voltage in section Operational Amplifier Fundamentals of Linear Integrated Circuits
