Since you asked this question three times, the way to ask it in correct English is as follows:

"Why can pair production occur only in an environment in which mass is present?"

The answer is that it does not require the presence of mass to occur.

You should have put the questions that are in the details of the other questions into the details of one question. If you did, you would have saved 10 points.

Hi. It doesn't. Particle / anti-particle formation and collapse occurs in a vacuum as well as in or near mass.
