Every fundamental charged particle has an antiparticle such that when the particle and antiparticle collide, they
annihilate each other to create two (uncharged) photons. What does conservation of charge imply about how a
particle's charge compares to that of its antiparticle? The particle's and antiparticle's charges
A. must be identical in sign and magnitude.
B. must have opposite signs and the same magnitude.
C. must have opposite signs, maybe different magnitudes.
D. must each be zero.
E. are not constrained at all by charge conservation.
