Rule 15 concerns Amended and Supplemental Pleadings.

• A. Amended and Supplemental Pleadings
• B. Discovery and Interrogatories
• C. Jury Instructions
• D. Pretrial Motions

Answer: (A)

Rule 15 governs Amended and Supplemental Pleadings. It covers how a party may change a pleading to add or modify claims or defenses (amendments) and how to bring in information that developed after the original pleading was filed (supplemental pleadings). Under Rule 15(a), a party may amend once as a matter of course before a responsive pleading is served; after that, amendments require the opposing party’s consent or the court’s leave. Rule 15(d) specifically addresses supplements to reflect events occurring after the pleading. This topic sits apart from discovery rules (such as discovery and interrogatories), jury instructions, and pretrial motions, which are governed by other rules.
