To find the number of triangles in the given figure, follow these steps:

1. Identify the smallest individual triangles in the figure. Count these smaller triangles. In this image, there are 4 smaller triangles formed in the bottom sections.
2. Find triangles formed by combining two or more smaller triangles. By combining:
   • Two adjacent small triangles, form one larger triangle. There are 2 such combinations possible.
   • All four smaller triangles at once form a bigger triangle, adding one more to the count.
3. Add the count of smaller triangles and larger triangles:
   • Smaller Triangles: 4
   • Larger Triangles from combinations: 2 + 1 = 3

Total number of triangles = 4 (small) + 3 (large) = 7 triangles.

Hence, the correct answer is 7.
