@Dheeraj
That's not 0.673, It is 0.0673.

@Sumit Kulkarni.
First, correct your calculations. (.0785-.0112=0.673).
Not (.0672).
And correct answer is, None of these, option D.

Curvature correction = 0.0785D^2.
Refraction correction= 0.0785D^2÷7 = 0.0112D^2.
Combined correction = (0.0785-0.0112)D^2 =0.0672D^2.
Refraction correction= 0.0785D^2÷7 = 0.0112D^2.
Combined correction = (0.0785-0.0112)D^2 =0.0672D^2.
