A fission reaction is given by `._(92)^(236)U rarr ._(54)^(140)Xe + ._(54)^(140)Xe + ._(38)^(94)Sr + x +y`, where `x` and `y` are two particles. Considering `._(92)^(236)U` to be at rest, the kinetic energies of the products are denoted by `K_(xe),K_(Sr),K_(x)(2MeV)` and `K_(y)(2Me V)`, respectively. Let the binding energies per nucleon of `._(92)^(236)U, ._(54)^(140)Xe` and `._(38)^(94)Sr` be `7.5 MeV, 8.5 Me V` and `8.5 MeV`, respectively. Considering different conservation laws, the correct options `(s)` is (are)

A

x = n , y= n , `K_(Sr) = 129` MeV , `K_(Xe) = 86 MeV`

B

x = p , y = `e^(-) , K_(Sr) = 129 MeV , K_(Xe) = 86` MeV

C

x = p , y =n , `K_(Sr) = 129 MeV , K_(Xe) = 86 MeV `

D

x = n , y = n , `K_(Sr) = 86 MeV , K_(Xe) = 129 ` MeV
