Which component is inherent filtration in dental X-ray equipment?

Explanation:
Inherent filtration is the filtration that comes from components built into the X-ray tube and housing before any added filters are used. The glass envelope of the X-ray tube (and the insulating oil around it) naturally absorbs some low-energy photons, reducing patient dose without any extra steps. That built-in filtration is why the glass envelope is the correct choice here. The aluminum sheet in the beam path is external filtration added to the beam to further reduce low-energy photons, not inherent. The lead apron is a protective shield for the patient, not part of the beam’s filtration. The collimator shapes the beam but does not filter photons. So the glass envelope provides the inherent filtration.
