If a wig has any handmade components, it is more expensive than one with none. Similarly, a made-to-measure wig ranges from medium-priced to expensive. Handmade foundations are never found on wigs that do not use human hair. Furthermore, any wig that contains human hair should be dry-cleaned. So all made-to-measure wigs should be dry-cleaned. The conclusion of the argument follows logically if which one of the following is assumed?
A: Any wig whose price falls in the medium-priced to expensive range has a handmade foundation.
B: If a wig's foundation is handmade, then its price is at least in the medium range.
C: Any wig that should be dry-cleaned has a foundation that is handmade.
D: If a wig's foundation is handmade, then it is more expensive than one whose foundation is not handmade.
Choose A, B, C or D as your solution.
