A
If both assertion and reason are true and reason is the correct explanation of assertion.
B
If both assertion and reason are true but reason is not the correct explanation of assertion.
C
If assertion is true but reason is false.
D
If both assertion and reason are false.

Resolution $=\frac{\text { Wavelength }(\lambda)}{\text { Diameter }(D)}$
