The answer is : D. Wind energy
Sulphur is found in 23 isotopes ranging from 27 to 49.
Also, magnitude of average atomic mass is more toward the isotope which is the most abundant.
Now , molecular mass of Sulphur is 32.06 u . It means the most abundant isotopes of Sulphur is 32.
It can also be verified by the fact that 95 % of natural occurring sulfur is .
Hence, this is the required solution.
