Best answer 11 votes 11 votes Option A is not a convex polygon as if we choose $\text{P}$ and $\text{Q}$ on the left-most tail the line segment $\text{PQ}$ will not be inside the polygon. zxy123 answered Feb 18, 2021 • edited Apr 17, 2021 by Lakshman Bhaiya zxy123 comment Share Follow See all 0 reply Please log in or register to add a comment.
