B)3
C)4
D)5
E)6

The question does not provide enough information to accurately determine the number of electrons emitted. However, since neither Ce-144 nor Sr-90 are known to emit electrons during radioactive decay, it is safe to assume that all of the electrons are emitted during the original nuclear reaction. Based on the conservation of charge, the total number of electrons emitted must balance out the overall charge of the products. Since both Ce-144 and Sr-90 have a charge of +2, and U-235 has a charge of +92, the total charge of the products is +96. In order to balance this out, four electrons would need to be emitted. Therefore, the correct answer is C) 4.
