answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.  

the correct answer is c
