Answer :

Simple curved figures : These figures are the figures which contain curved side in it. 

Simple closed curves : All the simple curved figures that are closed are called simple closed curves

Polygons : Polygons are closed figures that does not contain any curves. For example - triangle, rectangle, square, hexagon etc.

Convex polygons : A convex polygon is defined as a polygon with all its interior angles less than 180°. This means that all the vertices of the polygon will point outwards, away from the interior of the shape. 

Concave Polygons : A concave polygon is defined as a polygon with one or more interior angles greater than 180°. It looks sort of like a vertex has been 'pushed in' towards the inside of the polygon.

A. Simple curved figures are: 3, 5, 6, 7, 8

B. Simple closed curved figures are: 3, 5, 6, 7

C. Polygons are: 1, 2

D. Convex polygons are: 2
