Step 1: Understanding the Question:
The question tests our understanding of the legal definition of the term "cause of action."
We need to identify how this concept relates to the facts of a case, court orders, or the evidence presented by the parties.
Step 2: Detailed Explanation:
• A cause of action is legally defined as the "bundle of essential facts" that the plaintiff must prove in order to obtain a judgment or decree in their favor.
• It consists of two primary elements: the existence of a legal right in favor of the plaintiff, and the infringement of that right by the defendant.
• Every plaint must state the facts constituting the cause of action and when it arose, as required under Order VII Rule 1 of the CPC.
• Under Order VII Rule 11 of the CPC, a court is mandated to reject a plaint if it does not disclose a cause of action.
• It is not an interim order of the court, as interim orders are temporary reliefs granted during the pendency of a suit, making Option (B) incorrect.
• It is also distinct from the actual evidence or proof produced by the plaintiff or defendant in court, making Options (C) and (D) incorrect.
• Thus, Option (A) is the correct legal definition of a cause of action.
Step 3: Final Answer:
Legally, cause of action means the bundle of facts which give a person a right to sue for relief in court, which is Option (A).
