Swift Enums and Structs question

On the final quiz there is the question below. Which one of the following is a valid enum declaration?

Two answers are similar and I don't get why A is the correct one over C. Does the enum have to be capital or something?

A.) enum Genre { case Drama, Romance, Satire, Tragedy, Comedy } C.) enum genre { case drama, romance, satire, tragedy, comedy }

Hi, yes they have to be capitalized, according to the apple reference: Each enumeration definition defines a brand new type. Like other types in Swift, their names (such as CompassPoint and Planet) should start with a capital letter. Give enumeration types singular rather than plural names, so that they read as self-evident:

    var directionToHead = CompassPoint.West

Hope that helps!
