In a uranium reactor whose thermal power is `P=100 MW`, if the average number of neutrons liberated in each nuclear spitting is `2.5`. Each splitting is assumed to release an energy `E=200 MeV`. The number of neutrons generated per unit time is-
A. `4xx10^(18)s^(-1)`
B. `8xx10^(19)s^(-1)`
C. `8xx10^(19)s^(-1)`
D. `(125)/(16)xx10^(18)s^(-1)`
