How many squares can be identified in the figure ?

Correct option is D

Look at the figure — we need to count all squares (not triangles).

Step-by-step:

1. Small squares (1 block):
   There are 16 small squares in the grid.

2. Medium squares (2×2 blocks):
   You can find 4 of these.

3. Big square (whole grid):
   The entire figure is 1 big square.

4. Tilted (diamond-shaped) squares formed inside:
   There are 5 of these.

Total = 16+4+1+5=26
