EXPLAIN YOUR ANSWER ​

Answer 1

Answer:

A

Explanation:

A has the longest wavelength

If the hole is smaller than the wavelength, then the wavefronts coming out of the hole will be circular. Therefore, longer wavelengths diffract more than shorter wavelengths. The higher the diffraction, the easier you could see
