What is required alongside the complaint to support the allegations?

The correct choice indicates that additional documentation is necessary to bolster the allegations made in the complaint. This documentation serves as evidence to substantiate the claims and provide context for the allegations. By including relevant documents, such as contracts, emails, receipts, or any pertinent records, the party filing the complaint can help establish a clear connection between the asserted claims and the factual basis that supports them.

In legal proceedings, just stating a complaint is typically not sufficient; it must be accompanied by credible evidence that reinforces the claims being made. This ensures that the court or relevant body has sufficient information to assess the validity of the allegations and make informed decisions based on concrete evidence rather than mere assertions.
