If three different 741 op-amps are taken and the corresponding output offset voltage for each of them is measured. The output voltage in these three op-amps have

(a) Same amplitude and polarity

(b) Different amplitude and polarity

(c) Same amplitude and different  polarity

(d) Different amplitude and same polarity

The question was asked in an interview for internship.

Right answer is (b) Different amplitude and polarity

Expand on the concept with: Even though the op-amps are of the same type, the output voltage in these three op-amps are not of the same amplitude and polarity, because of mass production.
