The correct answer is:

D) MMR vaccine preservative (thimerosal).

Research has not supported the idea that thimerosal, a preservative previously used in some vaccines, is a cause of autism spectrum disorder (ASD). In fact, numerous studies have refuted the connection between vaccines and autism. In contrast, heritability, higher levels of serotonin, and lower activity levels in the amygdala are all areas that have been explored and have some research backing as potential factors related to ASD.
