Solution

The correct option is C $3$ and $4$ Only
We know, there are two basis on which triangles are subdivided.

One is on the basis of angle and another on the basis of sides.

On the basis of angles the triangles are divided as right-angled triangles, obtuse-angled triangles and acute-angled triangles.

And, on the basis of sides, triangles are divided as scalene triangles, isosceles triangles and equilateral triangles.

Hence, option $(c)$ correct.
