Step 1: Understanding the Question.
An injunction is a court order that prevents someone from doing something. A perpetual injunction is granted after the final hearing, and it prevents the defendant from asserting a right or performing an act that harms the plaintiff.
Step 2: Analysis of Options.
- (A) Temporary: A temporary injunction is granted before the final hearing, usually to maintain the status quo.
- (B) Perpetual: This is the correct answer. A perpetual injunction is granted after the hearing and continues indefinitely.
- (C) Both Temporary and Perpetual: This is incorrect because the question specifies a decree made after the hearing, which refers to a perpetual injunction.
- (D) None of these: This is incorrect since the correct answer is (B) Perpetual.
Step 3: Conclusion.
Thus, the correct answer is (B) Perpetual.
