`C_(14)` is a beta active nucleus. A sample of `C^(14) H_(4)` gas kept in a closed vessel shows increase in pressure with time . This is due to

Options

A. the formation of `N^(14)H_(3) and H_(2)`
B. the formation of `B^(14)H_(3) and H_(2)`
C. the formation of `C^(14) ._(2)H_(4)` and `H_(2)`
D. the formation of `C^(12) H_(3),N^(14)H_(2) and H_(2)`

Answer

A
