Given below are three schematic graphs of potential energy V(r) versus distance r for three atomic particles : electron `(e^(-))`, proton `(p^(+))` and neutron (n), in the presence of a nucleus at the origin O. The radius of the nucleus is `r_(0)`. The scale on the V-axis may not be the same for all figures. The correct pairing of each graph with the corresponding atomic particle is -

A

`(1,n), (2,p^(+)),(3,e^(-))`

B

`(1,p^(+)), (2,e^(-)),(3, n)`

C

`(1, e^(-)),(2, p^(+)),(3,n)`

D

`(1,p^(+)),(2,n),(3,e^(-))`
