The Correct answer is Option 1. 

Key Points

Identify the small “inner” triangles:

There are 6 small triangles formed directly by the intersecting lines.

Combine small triangles to form larger ones:

You can form 3 “medium” triangles by joining pairs of those small triangles.

You can form 2 more “medium” triangles by joining three small triangles at once.

Include the outermost triangle: The large boundary triangle itself counts as 1 more.

When you add them all up:

6 (small) + 3 (medium, using 2 small ) + 2 (medium, using 3 small ) + 1 (largest outer triangle) = 12 Triangles 

Hence Correct answer is Option 1.
