Materials of low mass are combined to form a substance of higher mass during . a. fission c. both A and B b. fusion d. neither A nor B Please select the best answer from the choices provided

The required "option is b) Fusion"

Explanation:

During fission, the nucleus of higher mass is broken down into the nucleus of lower mass in which a high amount of energy is released.During fusion two nuclei combine or fuses to form a larger molecule of higher mass for which a high amount of energy is provided.Therefore, the higher mass of a substance is formed with the combination of lower mass of a substance during the process of fusion.Hence, the required option is Fusion.
