Final answer:
In Louisiana, an employee or agent of the appointed process server is responsible for serving court papers, not the court clerk, plaintiff, or defendant.
Step-by-step explanation:
According to the process service laws in Louisiana, when the court appoints a process server, it is the employee or agent of the process server who must serve the papers. Neither the court clerk (option 1), the defendant (option 3), nor the plaintiff (option 4) are responsible for serving the papers in this situation.
The appointed process server's employee or agent is duly authorized to deliver the legal documents to ensure the defendant receives notice of the proceedings against them.
