Broadly speaking, what is a mathematical closure? O A. Only relations have closures. They are created by adding pairs until the relation has the desired property. O B. If X is a set, its closure under some property is the largest subset X* where the property is true of X*. O C. If X is a set, its closure under some property is the smallest superset X* where the property is true of X*.
