The first step in the proton-proton chain produces an antielectron,or positron.What happens to the positron?
A)It slowly works its way to the Sun's surface,where it escapes into space.
B)It rapidly escapes from the Sun,traveling into space at nearly the speed of light.
C)It is rapidly converted to energy when it meets an ordinary electron,resulting in matter-antimatter annihilation.
D)It quickly meets an ordinary electron,forming an electron-positron pair that remains stable.
E)It joins with a nearby neutron to form a proton.

The positron produced in the proton-proton chain is a type of antimatter and will rapidly undergo annihilation upon meeting an ordinary matter particle (in this case, an electron). This results in the conversion of their masses into energy, in accordance with Einstein's famous equation E=mc².
