In a Study Conducted by Miller and Maner (2010), Male

In a study conducted by Miller and Maner (2010) , male college students smelled T-shirts that had been worn under different conditions by four women as they slept. Some of the T-shirts had been worn by the women on the nights closest to ovulation, some on the nights farthest from ovulation, and some had never been worn. When the testosterone levels of the men were measured in the saliva samples:

A) there were no differences in testosterone levels across the different conditions.
B) the highest levels occurred after the men had smelled the T-shirts of the ovulating women.
C) the highest levels occurred after the men had smelled the T-shirts of the women who were not ovulating.
D) the highest levels occurred after the men had smelled the unworn T-shirts.
