Answer: she is expected to marry her husband's brother
Step-by-step explanation:
Levirate is derived from the latin word "levir" which means husband's brother. Levirate marriage is a marriage in which a woman is compelled to marry the brother of her deceased husband . This type of marriage is usually practiced in patriarchal societies that do not allow marriage outside one's social group or clan and most of these societies practice such to continue the line of the family especially if the widow has not borne any child with the deceased husband, or to give the new widow and her children protection and security.
