(B) IR²
Electric power is given by $P = VI = I^2R = V^2/R$. The expression $IR^2$ has no physical basis and does not represent electric power.

The examiner expects you to know the three standard formulae for electric power: $P = VI$, $P = I^2R$, and $P = V^2/R$. The term $IR^2$ is dimensionally incorrect for power and is the odd one out. Simply state the correct formulae and identify the incorrect one.
