Ultraviolet light of wavelength 300nn and intensity `1.0Wm^-2` falls on the surface of a photosensitive material. If one per cent of the incident photons produce photoelectrons, then the number of photoelectrons emitted per second from an area of 1.0 `cm^2` of the surface is nearly
A. `9.61 xx 10^(14)` per sec
B. `4.12 xx 10^(13)` pec sec
C. `1.51 xx10^(12)`
D. `2.13 xx 10^(11)` per sec
