问题 What is discovered by scientists at Brown University?

Scientists at Brown University in the Northeastern United States [27] discover that bacteria from yogurt can be made into a substance that helps fight HIV. Led by Professor Bharat Ramratnam, they modify the bacteria to cream cyanovirin—[28] a protein that protects the body from infection by microorganisms such as bacteria, viruses, and fungi. The hope is to use the bio-engineered yogurt bacteria as the active ingredient in a foam, cream or suppository that can be applied before sex to prevent HIV transmission.

选项 A、The inhibitor of the HIV transmission.
B、An effective way to deliver AIDS drugs.
C、A good strategy to prevent HIV transmission.
