Option B -- Most research underreports the number of gays and lesbians in a population

Explanation:

National Bureau of Economic Research is a private, nongovernment, non-biased, economic research establishment/organization, which is created purposely to give clear/more understanding about how economy works in both private and public sectors, by passing information on economic research among public policymakers, business men and women, and also in academic environment. Most of their research about lesbian and gay underreports the number of gays and lesbians in a population, because they were unable to get the exact numbers of gays and lesbian as at that time.

this null effect is caused by a weak manipulation and ineffective internal validity. in a scientific study, as the one dr. morimoto is trying to perfom, internal validity refers to the confidence placed in the cause-effect relationship and to how well an experiment is done and able to eliminate confounding variables.
