Answer:
B. They will be getting married.
Step-by-step explanation:
The most helpful hint for answering this question is Theseus's use of the phrase "nuptial hour". Nuptial is an adjective denoting something related to wedding or marriage. From that, it can be concluded that Theseus and Hippolyta are about to be married.
In this Shakespeare's play, Theseus is a ruler of Athens who declares a four-day festival of feast and entertainment to celebrate his marriage with Hippolyta.
This provides a setting and time-frame for the plot of this Shakespeare's comedy.
