C) Ovsynch is widely adopted because it allows a 100% submission rate (i.e., all cows injected are inseminated), in comparison to synchronization protocols based on insemination after estrus detection, which have lower submission rates because of heat detection errors.

A disadvantage of Ovsynch is that it is labor intensive. Ovsynch has no effect on the intensity or duration of estrus.
