Which of the following best describes the act of bigamy?

The act of bigamy is best described as being married to more than one person simultaneously. This definition captures the essence of bigamy, which is a criminal offense in many jurisdictions because it violates the legal principle of monogamy—the idea that an individual can only be legally married to one person at a time. Bigamy involves a deliberate intention to enter into a marriage while already being legally bound to another spouse, thereby creating legal and moral complications.

The other options refer to distinct actions related to marriage but do not accurately reflect the definition of bigamy. For instance, marrying without a legal license pertains to the legality of the marriage initiation, and marrying someone not of legal age involves concerns about age-related consent rather than the number of spouses. Divorcing without proper legal process relates to the dissolution of marriage rather than the status of being married to multiple people at the same time.
