Which one of the following statements is true about the small signal voltage gain of a MOSFET based single stage amplifier?

Assuming ideal op-smps, the circuit represents is

The I-V characteristics of the elements between the nodes X and Y is best depicted

A nullator is defined as a circuit element where the voltage across the device and the current through the device are both zero. A series combination of a nullator and a resistor of value, $R$, will behave as a

Consider a discrete-time linear time-invariant (LTI) system, $S$, where
$y[n]=S\{x(n)\}$.
Let $S\{\delta [n]\}=\{\begin{array}{ll}1,& n\in \{0,1,2\}\\ 0,& \text{otherwise}\end{array}$
where $\delta [n]$ is the discrete-time unit impulse function. For an input signal $x[n]$, the output $y[n]$ is
