Pair production is just oppsite to mass annihilation. When suddenly &gamma; ray energy disappears to form a pair of a particle and an anti-particle, the process is called pair production.

Q. The phenomenon of pair production is

ejection of an electron from a nucleus

ejection of an electron from a metal surface

ionization of a neutral atom

the production of an electron and a positron from $γ -$ rays.

Pair production is just oppsite to mass annihilation. When suddenly $γ$ ray energy disappears to form a pair of a particle and an anti-particle, the process is called pair production.
