In the Bohr's model of hydrogen atom, the electron moves around the nucleus in a circular orbit of radius \[\text{5 }\times \text{1}{{0}^{-\text{11}}}\] metres. If its time period is \[\text{1}.\text{5 }\times \text{ 1}{{0}^{-\text{16}}}\] sec, then current associated with the electron motion is

A)  zero                     

B)         \[\text{1}.\text{6 }\times \text{ 1}{{0}^{-\text{19}}}\text{ A}\]

C)  00.17 A            

D)         \[\text{1}.0\text{7 }\times \text{1}{{0}^{-\text{3}}}\text{ A}\]
