Explanation: a p e x

Mass is converted to the energy binding a nucleus together cause a mass defect.Hence , Option (C) is correct.
What is Mass defect ?
The actual atomic mass is less than the predicted mass calculated by adding the masses of nucleons.
This additional mass is accounted for by binding energy that is released when a nucleus is formed.
When a nucleus is formed, some of the mass is converted to energy and this results in the mass defect.
Therefore, Mass is converted to the energy binding a nucleus together cause a mass defect. Hence , Option (C) is correct.
