Answer:

Explanation:

The binding energy per particle (B.E./A) in MeV is a measure of the energy required to separate a nucleus into its individual protons and neutrons. The histogram shows the B.E./A as a function of the mass number A of a nucleus. When a nucleus with mass number A = 180 fissions into two nuclei of equal masses, the process releases energy. The amount of energy released can be calculated by looking at the difference in B.E./A between the original nucleus and the two resulting nuclei. Since the two resulting nuclei have half the mass number of the original nucleus, the B.E./A for each will be higher. Therefore, the process releases energy and the answer is (C) 360 MeV of energy is released.
