In the circuit shown below, 
and 
are bias voltages. Based on input and output impedances, the circuit behaves as a
voltage controlled voltage source.
voltage controlled current source.
current controlled voltage source.
current controlled current source.
Explanation:
In the given circuit,
Transistor 
is common-gate amplifier and transistor 
behaves as an active load.
By using properties of common gate (CG) amplifier,
Input impedance 
is low
Output impedance 
is high
So, it is a current amplifier.
Current amplifier is a current controlled current source.
