A physical quantity of the dimensions of length that can be formed out

1.	A physical quantity of the dimensions of length that can be formed out of c, G and (e^2)/( 4pi in_0) is [ c is velocity of light, G is universal constant of gravitation and e is charge ]:
Answer» `(1)/( C) G (E^2)/( 4PI in_0)` `(1)/( c^2) [ G(e^2) /( 4pi in_0) ]^(1//2)` `e^(2) [G (e^2)/( 4pi in_0) ]^(1//2)` `(1)/( c^2) [ (e^2)/( G4pi in_0) ]^(1//2)` Answer :B
