The only source of energy in a particular star is the fusion reaction given by -
`3._(2)He^(4)to._(6)C^(12)`+energy
Masses of `._(2)He^(4)` and `._(6)C^(12)` are given
`(m._(2)He^(4))=4.0025 u, m(._(6)C^(12))=12.0000u`
Speed of light in vaccume is `3xx10^(8) m//s`. power output of star is `4.5xx10^(27)` watt. The rate at which the star burns helium is

`8xx10^(12)`

`4xx10^(12)`

`12xx10^(13)`

`9xx10^(13)`
