I94 most likely. Visa is valid for 3 months is okay, that just means that they have to travel within 3 months (to enter U.S. by the expiration date).
The thing that determines how long they can stay is the I94. For B2, they most likely will issue an I94 valid for 6 months.
This happened to my parents.
