alright , then i am glad to help :D

well, thanks

anonymous · Answer

The answer is A. As you can easily calculate mass defect value by basic knowledge. And the change in mass is thus governed by this eqn. As the mass changes due to emmision of antineutrino particle which travels with the speed of light and releases energy in the form of E.M. Radiation

I would say A

Just look at the question. "often used DIRECTLY" 

Out of your questions  only A says something about energy  as a product of something.
