Find the output voltage and the load current for the circuit given below. Assume that the op-amp is initially nulled V1 =2.5v

(a) IL=0.42mA, Vo =10v

(b) IL=0.42mA, Vo =3.4v

(c) IL=0.42mA, Vo =6.1v

(d) IL=0.42mA, Vo =5v

I got this question by my school principal while I was bunking the class.

My query is from Voltage to Current Converter with Floating and Grounded Load in chapter Operational Amplifier Applications of Linear Integrated Circuits

The correct answer is (d) IL=0.42mA, Vo =5v

Expand on the concept with: The load current IL =vin /R =5/12kΩ =0.42mA

vo =IL×R, can be obtained when Vo=2×V1 = 2×2.5 =5v.
