In the nuclear transmutation
`""_(4)""^(9)Be+Xto""_(4)""^(8)Be+Y`, (X,Y) is(are):

In the nuclear transmutation ""_(4)""^(9)Be+Xto""_(4)""^(8)Be+Y , here (X,Y) is/are:

In the nuclear transmutation, ""_(4)^(9)Be + X to ""_(4)^(8)Be + Y . X and Y are :

In the nuclear transmutation : ._(4)^(9) Be + X rarr _(4) ^(8) Be +Y (X,Y) is (are)

In the nuclear transmutation ._(4)Be^(9)+X rarr ._(4)Be^(8)+Y (X,Y) is // are

In the nuclear transmutation ._(4)Be^(9)+X rarr ._(4)Be^(8)+Y (X,Y) is // are
