Step 1: Understanding Vis Major.
Vis major is a legal term referring to "force majeure," which signifies an event beyond human control, often referred to as the "Act of God." It typically refers to natural disasters such as floods, earthquakes, or other unforeseeable events that prevent the fulfillment of contractual obligations.
Step 2: Explanation of the options.
- (a) Act of God: This is the correct answer, as vis major refers to events outside human control, such as natural disasters.
- (b) Act of Individual: This is incorrect, as vis major does not refer to actions taken by individuals.
- (c) Act of other party: This is incorrect, as vis major is about uncontrollable natural events.
- (d) Act of plaintiff: This is incorrect, as vis major refers to external uncontrollable factors, not the actions of the plaintiff.
Step 3: Conclusion.
Thus, the correct answer is (a) Act of God.
