The answer is: B
Explanation
The correct option is B: Perpetual.
A perpetual injunction is one that is granted by the decree made at the hearing and upon the merits of the suit; the defendant is thereby perpetually enjoined from the assertion of a right, or from the commission of an act, which would be contrary to the rights of the plaintiff. This is the definition given by Section 37(2) of the Specific Relief Act, 1963. A temporary injunction, on the other hand, is one that is granted at any stage of the suit and lasts until a specified time or further order of the court. A temporary injunction is regulated by the Code of Civil Procedure, 1908, while a perpetual injunction is governed by the Specific Relief Act, 1963.
