Limitation of an output stage amplifier, if it emitter follower with complementary transistor

(a) Cross-over distortion

(b) Low impedance output

(c) Shift in level

(d) Active load current

The question was posed to me by my college professor while I was bunking the class.

This intriguing question comes from Operational Amplifier Internal Circuit topic in chapter Operational Amplifier of Linear Integrated Circuits

The accurate option is (a) Cross-over distortion

Breaking it down, I'd say: The limitation in the amplifier is that , the output voltage remains zero until the input voltage exceeds cut in voltage VBE= 0.5v, which is known as cross-over distortion.
