To calculate the reticulocyte count: 
1. Count the number of reticulocytes in the larger square (25 in this case) 
2. Count the number of red cells in the smaller square (900 in this case) 
3. Divide the number of reticulocytes by the number of red cells and multiply by 100 to get the percentage.

So, Reticulocyte count = (25/900) x 100 = 2.7% which is closest to C) 0.3%
