Question

Accepted Answer

A. {'text': 'Sharing intravenous needles', 'label': 'A'}

1. HIV spreads through blood, semen and vertical transmission (mother-to-child).
2. Condoms, safe blood screening and public education all reduce risk.
3. Sharing intravenous needles INCREASES the risk — it is a major transmission route.
4. So the "not a preventive measure" is the sharing of needles.
