A reason is an explanation or justification for the assertion. In this case, the reason provided is that "Sodium ion has more protons than a neutral atom."
Sodium (Na) has 11 protons in its neutral atom. When it loses an electron, it becomes a positively charged ion, known as a sodium cation (Na+). Since it has lost an electron, it now has 11 protons and only 10 electrons, thus resulting in a net positive charge. This is why the assertion that "A sodium ion has a positive charge" is true, and the reason "Sodium ion has more protons than a neutral atom" is a valid explanation for the assertion.
