With no explanation, chose the best option from "A", "B", "C" or "D". was a matter for the arbitrator to decide).

See supra note 4. Bell and its Union agree that disputes over the reorganization of administrative groups may be resolved through arbitration; they simply disagree on the procedures to be followed. The Union has asked that both of these issues — the reorganization dispute and the procedure to be followed — be submitted to an arbitrator, and we hold that this is the proper course for the parties. See John Wiley & Sons, 376 U.S. at 558, 84 S.Ct. 909 (<HOLDING>). The District Court’s judgment will be

A: holding that the information must establish that the court has jurisdiction over both the subject matter and the parties
B: holding that the court must send the parties to arbitration in cases in which arbitrability of the subject matter is unquestioned but a dispute arises over the procedures to be followed
C: holding that a gateway dispute about whether the parties are bound by a given arbitration clause raises a question of arbitrability for a court to decide
D: holding that because a valid arbitration clause existed the parties had to arbitrate all disputes when the subject matter of the dispute has a reasonable relationship to the subject matter of the contract
