If T is the time required by electron in taking one round in an orbit, n represents the number of waves in an orbit, r represents the radius of orbit, then which have the value of 1/2 for `2^(nd)` orbit of H and `4^(th)` orbit of `He^(+)` ?

A

`(r_(2(H)))/(r_(4(He^(+))))`

B

`(T_(2(H)))/(r_(4(He^(+))))`

C

`(n_(2(H)))/(n_(4(He^(+))))`

D

`(E_(2(H)))/(E_(4(He^(+))))`
