Step 1: Understanding the Concept:
Order VI Rule 16 of the CPC, 1908, grants the court the power to "strike out" pleadings that are unnecessary, scandalous, frivolous, or vexatious to ensure a fair and efficient trial.
Step 2: Detailed Explanation:
- The court has the authority to strike out or amend any matter in any pleading if it is found to be unnecessary, scandalous, or if it tends to prejudice, embarrass, or delay the fair trial of the suit.
- Crucially, this power can be exercised "at any stage of the proceedings." It is not limited to a specific time before the trial begins, allowing the court to maintain procedural order throughout the litigation.
Step 3: Final Answer:
The correct action is to strike out such pleadings at any stage. Option (C) is the correct answer.
