Which statement best describes gamma and X-ray particles?

Explanation:
Gamma and X-ray radiation are forms of electromagnetic radiation that come as photons. Photons have no rest mass and no electric charge, yet they carry energy and momentum. Because they are neutral and massless (in the sense of rest mass), they interact differently with matter than charged particles, allowing them to penetrate many materials more effectively. That combination—no charge and no mass, with high penetrating power—is why this statement is the best description. Other options don’t fit because photons are not charged and not massive; they do carry energy but not rest mass, and they are not positively charged.
