A plaintiff, an art collector, brought a declaratory judgment action in federal district court seeking a declaration that he was the owner of a painting. In his complaint, the plaintiff alleged that he had recently purchased the painting for value and in good faith. The defendant, in her answer, did not challenge the plaintiff's assertions. The defendant, however, did allege that the painting had been owned by her mother and was fraudulently sold several years earlier by her father, without her mother's consent, to an art dealer in order to support her father's gambling habit. The defendant contended that she became the rightful owner of the painting as devisee of her mother's personal property after her mother's death. Also in her answer, the defendant asserted that the court lacked personal jurisdiction over her because she was a lifelong citizen of a state other than the forum state. The painting is hanging in the plaintiff's residence, which is located in the forum state. Does the court have personal jurisdiction over the defendant?
a. Yes, because the painting is located in the forum state.
b. Yes, because the defendant has filed an answer.
c. No, because possession of the painting was allegedly lost due to fraud.
d. No, because the defendant is not a citizen of the forum state.
