A transportation company from State A sued a tourism company from State B in federal court for breach of contract seeking $76,000 in damages. The transportation company filed an appropriate demand for a jury trial, and both parties stipulated that the jury would consist of 10 people. Following the trial and deliberations, nine of the jurors voted in favor of the plaintiff for $29,000 in damages, but one juror voted for the defendant. The defendant appealed. On which of the following grounds would the defendant most likely prevail on appeal?
A The court lacked subject matter jurisdiction because the verdict did not exceed $75,000.
B The court lacked personal jurisdiction.
C The ruling was defective because the jury's vote was not unanimous.
D The ruling was defective because it was rendered by fewer than 12 jurors.
