Which character is known as Fred Flintstone's wife?

Wilma Flintstone is the character known as Fred Flintstone's wife in the animated television series "The Flintstones." She is depicted as a strong, caring, and resourceful partner who often supports Fred in his endeavors, even when they lead to humorous trouble. The dynamics of their relationship are central to many storylines, showcasing themes of family and community life in the Stone Age, albeit in a comedically modern context.

The other choices represent characters related to the Flintstones universe but do not hold the title of Fred's spouse. Betty Rubble is Wilma's best friend and the wife of Barney Rubble. Pebbles Flintstone is the daughter of Fred and Wilma, while Barney Rubble is Fred’s best friend and neighbor. Each of these characters contributes to the narrative but none share the same role as Wilma, who is integral to defining the identity of the Flintstone family.
