Answer:
Yes because both the plaintiff corporation and the defendant corporation have a common state citizenship
Step-by-step explanation:
A federal court can have federal subject-matter jurisdiction over a case based on diversity jurisdiction, in which is required the jurisdictional amount is more than $75,000 and that non of the plaintiffs has the same citizenship of a state as any of the defendants
The citizenship of a corporation is both the state of incorporation and the corporation's principal place of business
Given that the plaintiff corporation was incorporated in State B and has State C as its principal place of business, the citizenship of the plaintiff corporation is both State B and State C
Similarly, the defendant corporation's citizenship, based on the state the corporation was incorporated and the state of principal place of business are State C and State A
Therefore, the plaintiff corporation and the defendant corporation have the same citizenship of a state, which is State C, and the defendant corporation's motion will be granted
