Answer: C. No, because the federal rules permit service under the rules of the state in which service will be effected.
Step-by-step explanation:
The case was filed in federal court so the rules regarding the service of the summons will be according to the rules of federal courts.
Rule 4 of the Federal Rules of Civil Procedure allows for the service of a summons to be based on the service rules of the state where the service is to be made. As the service was done in State A and State A allows service to be at defendant's place of business, proper procedure was followed and so the court will not dismiss the action.
