Sociologist Laud Humphreys’s study on social interaction in “tearooms,” public restrooms where some men go for quick, anonymous oral sex with other men, is an example of which type of study?

The correct answer is A. participant observation.

Laud Humphreys’s study involved him directly observing social interactions in tearooms while acting as a “watchqueen,” which means he engaged in participant observation. This approach allows researchers to gain insights into social behaviors and interactions by immersing themselves in the environment they are studying, rather than just surveying or collecting data through other means.
