I think it is d, where matter is obviously a source for energy, but energy is not matter, and you'd need an extremely large amount of energy to even change existing matter into another, such as with nuclear fusion...
SO, answer D.

Silly, E = MC2
As Einstein pointed out, energy is mass times velocity squared. The main difference is that matter is particulate and energy can simply be wave motion. As far as the best theories go, D would be most correct as the second law of thermodynamics states that all mass is degrading into pure energy over time. At some point, there will be nothing left.

Anything that occupies space is called matter.Energy is the capacity for doing work.All forms energy are .from matter.Potential energy is due to gravitational force. Electromagnetic energy also needs matter. The other forms of energy also needs matter.We cannot get energy from emptiness.

Try asking this in physics instead of biology....
But, I'm pretty sure d is the right answer.
