Answer:

Option D, 13

Step-by-step explanation:

A polygon is such that when all diagonals from on vertex are drawn, eleven triangles are formed.

We have to tell number of sides of the polygon.

Since number of triangle"y" formed by "n" number of vertices can be represented by (n-2) = y

By putting y = 11 in the equation

11 = (n-2)

n = 13

Option D is the answer.
