d. all of the above
e. none of the above

Promiscuous humans should have reduced levels of : c. oxytocin

Explanation:

Prairie voile are known as monogamy animals. In many experiments the researchers found that when they administrate oxytocin to the animals reward system in their brains is activated and bonds whit their partners were stronger. This experiment helped to infer the theory of monogamy and its relation whit chemical hormones specially whit oxytocin. This neural effect is cause by two parts of brains connections between their prefrontal cortices which is associated with decision-making and their nucleus accumbens which is associated with reward system. That’s probably why promiscuous humans should have reduced levels of oxytocin.
