Answer
- [x] d) A is false but R is true
Assertion is false: endoscopes are heat-sensitive, semi-critical items and are not sterilized by autoclave (steam autoclaving would damage their delicate optical/mechanical components); per Spaulding’s classification, they instead require high-level disinfection (e.g., glutaraldehyde, ortho-phthalaldehyde) as semi-critical items, or low-temperature sterilization methods (e.g., ethylene oxide, plasma) where full sterilization is required.
Reason is true: endoscopes are indeed heat-labile (the reason correctly states this, aside from the minor typographical rendering “heat Labine” for “heat labile” in the ingested question text).
Since the Assertion is false and the Reason is an independently true statement (and, indeed, is precisely why the assertion’s claimed practice would be inappropriate — though the assertion itself remains false, not explained-by-reason-as-being-true), the correct option is that A is false but R is true.
