Question $2(1$ point$)$

Consider the following circuit.

How many supernodes are present in this circuit?

There are zero $(0)$ supernodes in that circuit.

There are two $(2)$ supernodes in that circuit.

There are three $(3)$ supernodes in that circuit.

There are five $(5)$ supernodes in that circuit.

There are eight $(8)$ supernodes in that circuit.

There are nine $(9)$ supernodes in that circuit.

We cannot tell! Supernodes only come out at night, when disaster strikes or evildoers are afoot. By day they are mild$-$mannered ordinary nodes.
