P sued D in federal court. P alleged federal question jurisdiction existed over their claim. D brought a compulsory counterclaim against P for $60,000. P impleaded a third party, claiming the third party was liable to indemnify P if P were found liable for D's counterclaim. P is a citizen of State X. D is a citizen of State Y. The third-party defendant is a citizen of State X. The third-party defendant moved to dismiss the claim against them for lack of subject matter jurisdiction. The court should 

 a) Deny the motion because federal question jurisdiction provides subject matter jurisdiction over the claim. 

b) Deny the motion because supplemental jurisdiction provides subject matter jurisdiction over the claim. 

c) Grant the motion because the third-party defendant is a citizen of State X.

d) Grant the motion because the amount in controversy is not met
