Answer:
The correct answer is letter "A": be sanctioned under Rule 11 of the Federal Rules of Civil Procedure.
Explanation:
Rule 11 of the Federal Rules of Civil Procedure states that a court can sanction a party involved in a trial because of presenting inconsistent arguments against another individual. Section (b)(2) of the rule established that claims, defenses or legal contentions must be unfrivolous and that allegations have evidentiary support or that it must be reasonable enough to start an investigation.
Otherwise, monetary sanctions can apply if there is a violation of subdivision (b)(2).
