Answer:
D. Obtain an official record that the filing has been made.
Step-by-step explanation:
Obtaining an official record that the filing has been made is a guideline for a successful complaint filing. This is important because it provides proof that the complaint has been filed within the required timeframe, which is necessary to ensure that the complaint is considered valid and can proceed through the appropriate legal channels. It also serves as a record of the complaint that can be referenced in the future if necessary. Accurately digesting and indexing, managing the calendar and scheduling, and delivering the complaint in person to the defendant may be important steps in the complaint filing process, but they are not necessarily guidelines for a successful complaint filing.
