In the circuit, 
is an ideal current source. The transistors 
and 
are assumed to be biased in saturation, wherein 
is the input signal and 
is fixed DC voltage. Both transistors have a small signal resistance of 
and trans-conductance of 
. The small signal output impedance of this circuit is
infinity
Explanation:
Transistors and are biased in saturation.
In AC analysis: (DC Supply) = Short Circuited
Current Source = Open circuited
Concept:
where 
Option (c) is correct.
