Answer:
(B)
step by step explanation:
Convex Octagon: A convex octagon has no angles pointing inwards. Also, no internal angles can be more than 180°.
Concave Octagon: When any internal angle is greater than 180° it is concave.
Convex heptagon: A convex heptagon is a seven-sided polygon in which we can connect any two of its vertices with a line segment.
Concave heptagon: If any internal angle is greater than 180° then the polygon is concave.
Now, in the given figure, it can be seen that the number of the sides are seven and also one angle is greater than 180° , thus the given figure is concave heptagon.
Hence, option B is correct.
