Answer:
B. Bi-214.
Explanation:
The equation shows beta particle emission of 214/82 Pb which result into 214/83 Bi, in which the mass remain same but the the atomic number increases by one.
During this emission neutron get split into an electron and a proton which are represented as 0/e/-1.
So, the final nuclear equation becomes : 214/82 Pb => 0 e -1 + 214/83 Bi
Hence, the correct answer is "B. Bi-214."
