Answer:

The answer is C

Explanation:

If we assume the sum of energy that could be obtained by absolutely transforming a unit of length, m. It is compared to the speed of light in this connection. In this case, the whole mass of the electron becomes force. In this, depending on the relation of Einstein, each electron can generate 510 keV, which is why only the option of "c" is right.
