• A. Signing Pleadings, Motions, and Other Papers; Representations to the Court; Sanctions
• B. Evidence discovery and admissibility
• C. Trial instructions and rulings
• D. Appellate procedure

Answer: (A)

Rule 11 deals with the signing of pleadings, motions, and other papers; representations to the court; and sanctions. It requires that filings be signed by an attorney or party, with a certification that, after reasonable inquiry, the filing is not for an improper purpose, the claims or defenses are warranted by law or are nonfrivolous, and the factual contentions have evidentiary support. If those representations are false or the filing is improper, sanctions may be imposed. The other topics listed correspond to different areas of procedure—discovery and evidence, trial instructions and rulings, and appellate procedure—so they don’t fit Rule 11 as well as the signing, representations, and sanctions focus.
