[2025-10-02T07:25:04.774187] [PI reasoning] **Identifying AIDS discovery date**

I'm looking to confirm the discovery date of the causative agent of AIDS. The HIV virus was identified in 1983 by Luc Montagnier's team at the Pasteur Institute, and also in 1984 by Gallo. So, the clear answer is 1983, which I can confidently state. I’ll include a citation from Barré-Sinoussi et al. 1983 in Science, with PMID 6189183. This leads me to conclude that the answer is letter B.
