Apositively charged atom has lost electrons lost protons gained electrons gained protons

A positive charged atom has lost electrons.

Electrons are present in the outer shell of an atom, loosely bond to the nucleus, the only binding force on the electrons is the electric force, while the protons are inside the nucleus, and tightly bond to the nucleus by nucleus binding force, therefore an atom can only be positively charged when it loose electron from the shall.

i guess it’s a and b
