What is the minimum total energy released when
an electron and its antiparticle (positron)
annihilate each other?
(1) 1.64 × 10^–13 j (3) 5.47 × 10^–22 j
(2) 8.20 × 10^–14 j (4) 2.73 × 10^–22 j

Explanation:

Energy released in this process is given by

here we have

since here mass of two electrons converted into energy so we have

so here energy released is the energy of rest mass energy due to two charges i.e. electrons and positrons

this is poiselle's equation from fluid mechanic in physics. mech eng

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
