Answer:
The correct answer is letter "B": Forum selection clause.
Step-by-step explanation:
A forum selection clause is a provision stated in a contract by which both parties agree that in front of litigation only a specific forum will be selected. This clause is enforceable unless the party unwilling to accept the provision proves it is unreasonable because of a determined circumstance. In case the parties decide not to litigate, this clause encourages settlement in a selected forum.
