X-ray and gamma-ray photons share the same fundamental nature: both are electromagnetic radiation, massless energy packets (photons) that travel at the speed of light and can ionize matter. Their similarities come from this EM-wave character, which governs how they interact with tissues in imaging and shielding. The key difference lies in how they’re produced—gamma rays come from nuclear transitions, while X-rays result from high-energy electrons interacting with matter or decelerating in an x-ray tube. Because of their shared electromagnetic nature, X-rays are very much the same as gamma rays in terms of behavior as radiation, making gamma rays the best match. The other options describe particles or non-existent terms, which don’t fit the concept of electromagnetic radiation.
