Certain characteristic wavelength in the light from a galaxy in the constellation virgo are observed to be increased in wavelength, as compared with terrestrial sources, by about `0.4%`. What is the radial speed of this galaxy with respect to earth ? Is it approacing or receding ?

A

Moving away with velocity `1.2 xx 10^(6) m//s`

B

Coming closer with velocity `1.2 xx 10^(6) m//s`

C

Moving away with velocity `4 xx 10^(6) m//s`
