How is mass-energy equivalence demonstrated in the Sun?

A
Hydrogen nuclei fuse to form a larger nucleus, and a small amount of mass is converted into energy.
B
Hydrogen nuclei fuse to form a larger nucleus by absorbing a large amount of energy and converting it into a small amount of mass.
C
Hydrogen nuclei form from smaller nuclei, and a small amount of mass is converted into energy.
D
Hydrogen nuclei form from smaller nuclei by absorbing a large amount of energy and converting it into a small amount of mass.
