Solution

The correct option is D: $(n - 3)$
A diagonal is a segment that connect two non-consecutive vertices in polygon.
The number of diagonal in a polygon that can be drawn from any vertex in polygon is three less than the number of sides.

Let $n$ be the number sides in polygon.

So, the number of diagonals drawn from the vertex of polygon of $n$ sides is $(n - 3)$ .
