Which is a common exposure route for Bisphenol-A (BPA)?

Explanation:
BPA exposure is mainly through ingestion when BPA-containing plastics transfer the chemical into what you drink or eat. Degraded plastic in water bottles is a common route because as plastic ages, scratches, or is heated (for example, in a microwave or dishwasher), BPA can migrate out of the plastic and into the liquid you consume. This is why many health-focused discussions emphasize avoiding heating foods or liquids in plastic containers or using BPA-free alternatives. The other options describe exposure to entirely different hazards (lead contamination, asbestos dust) or factors (sunlight) that do not describe BPA entering the body.
