Solution

The correct option is C $a \to h; b \to f; c \to e; d \to g$
Power is a scalar quantity since it has magnitude only.
A vector divided by its magnitude gives us a unit vector in the direction of the given vector.
Angular velocity is an axial vector.
$\to A + \to B = \to A - \to B$
$\to A$ cancels out from both side giving $\to B = 0$ .
