How are the arbitrary signal represented, that are applied to the input of transistor? (Assume common mode signal and differential mode signal to be VCM & VDM respectively).

(a) Sum of VCM & VDM

(b) Difference of VCM & VDM

(c) Sum and Difference of VCM & VDM

(d) None of the mentioned

The question was asked in my homework.

My doubt is from Operational Amplifier Internal Circuit topic in chapter Operational Amplifier of Linear Integrated Circuits
