Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given a figure which has nine sides.
So it is known as "Nonagon".
As we know that "Convex polygon is a polygon that has all its interior angles less than 180°.
Otherwise, it is known as "Concave polygon".
So, from the graph we can depict that it is a convex nonagon.
Hence, Option 'A' is correct.
