The correct answer for the given statement above would be option D. The statement that correctly answers whether the question of alien life on the moon is scientific is, the question is scientific because it is testable and verifiable. Testable and verifiable in a way that it is possible to conduct tests or experiments to prove whether the given claim is true or not. A scientific statement is based on objectivity.

Not to be too picky, but the question ought to say a positively charge ion rather than atom.
I will assume that is what you mean. An ion, using ordinary means, will be positive if it loses electrons (which are negative).
An ion can never gain protons. Left alone, the nucleus will remain unchanged for the rest of eternity. D is wrong.
C is wrong. If electrons are gained, the ion will go negative.
B is wrong for the same reason D is. An ion can't gain protons and it can't lose them.
A is the answer.
