Between 0 and 
D
Equal to that of an electron
Text Solution
Verified by ExpertsThe correct answer is:
A
Step 1: Understand that photons are massless particles.
Step 2: According to Einstein's theory of relativity, the rest mass of a photon is zero because it travels at the speed of light.
Therefore, the correct answer is A.
