Order VI rule 16 CPC lets the court, at any stage of the proceedings, strike out or amend any matter in a pleading that is unnecessary, scandalous, frivolous or vexatious, that may tend to prejudice, embarrass or delay the fair trial of the suit, or that is otherwise an abuse of the process of the court. Each listed ground is in the rule, so "All of the given options are correct".

Current law: The relevant central CPC rule remains materially unchanged for ordinary civil suits.
