Final answer:
Option (B), The research aimed at developing a vaccine for HIV/AIDS is classified as Applied Research, focusing on practical solutions to health issues.
Step-by-step explanation:
The research aimed at finding a vaccine to prevent HIV/AIDS infection would be classified as Applied Research. This type of research seeks to resolve specific, practical problems, as opposed to Pure Research, which is primarily concerned with gaining knowledge without immediate practical application.
In the context of HIV/AIDS, while pure research might involve studying the behavior and transmission of the virus, applied research is directly involved in creating solutions, such as developing a vaccine to prevent the infection. The pressing need to address the ongoing public health crisis posed by HIV/AIDS, especially among populations with poor access to healthcare, underscores the significance of applied research in the biomedical field.
