Which title is held by a leader of a single congregation in the Latter-day Saints faith?

In the Latter-day Saints faith, the title held by a leader of a single congregation is "Bishop." Bishops are responsible for the spiritual and administrative needs of their congregation, known as a ward. They provide guidance, oversee programs, and tend to the welfare of their congregation members. The role of a bishop is significant within the church structure, as they have authority to perform baptisms, preside over meetings, and offer counsel to members.

The other titles listed do not accurately reflect the leadership structure in the Latter-day Saints faith. Cardinals are associated with the Roman Catholic Church and oversee large geographical areas or specific roles within the church. Priests, while also a relevant title, do not typically represent or lead individual congregations in Latter-day Saints practice; that role is specifically assigned to bishops. Monks are generally associated with religious orders in Christianity that involve a commitment to monastic life, and are not tied to the leadership of congregations in the context of the Latter-day Saints. Therefore, the title that correctly describes the leader of a single congregation in this faith is bishop.
