Write the equation for change in the output offset voltage?

(a) △Voo = [-RF/R1)]× [△Vio/△V] ×△V

(b) △Voo = [1+(RF/R1)]× [△Vio/△V] ×△V

(c) △Voo = [1+(RF/R1)]× [△Vio/△V].

(d) None of the mentioned

This question was posed to me during an interview for a job.

I'd like to ask this question from Effect of Variation in Power Supply Voltage on Offset Voltage topic in chapter Operational Amplifier Fundamentals of Linear Integrated Circuits

Correct choice is (b) △Voo = [1+(RF/R1)]× [△Vio/△V] ×△V

Unravel the mysteries with: The change in the input offset voltage is given as

 △Voo =[1+(RF/R1)]× [△Vio/△V] × △V

Where, △V = Change in supply voltage +Vcc & -Vee,

△Vio/△V = Supply voltage rejection ratio (µV/V) and

[1+(RF/R1)] = Gain of the differential amplifier.
