Define total current (IQ) equation in differential amplifier with constant current bias current

(a) IQ=1/R3×(VEE/R1+R2)

(b) IQ =(VEE×R2)/(R1+R2)

(c) IQ=1/R3×(VEE×R2/R1+R2)

(d) IQ)=R3×(VEE/R1+R2)

The question was posed to me in an online interview.

I'm obligated to ask this question of Operational Amplifier Internal Circuit in section Operational Amplifier of Linear Integrated Circuits

The correct answer is (c) IQ=1/R3×(VEE×R2/R1+R2)

Here's the scoop: The equation for total current is obtained by applying Kirchhoff’s Voltage Law to constant current circuit in differential amplifier.
