The correct answer is: A. Invalid
A promise is a legally binding agreement between two or more parties. In order to be valid, a promise must meet certain requirements, including:
- The parties must have the legal capacity to enter into a contract.
- The parties must intend to be legally bound by the promise.
- The promise must be supported by consideration.
- The promise must be for a legal purpose.
In the case of Mr. X’s promise to pay Mr. Y Rs. 5,000, 7 days after the death of Mr. Z, the promise is invalid because it does not meet the requirement of being for a legal purpose. A promise to pay money after the death of another person is considered to be a wagering contract, which is illegal in most jurisdictions.
Here is a brief explanation of each option:
- Invalid: A promise is invalid if it does not meet the requirements of a valid contract.
- Valid: A promise is valid if it meets all of the requirements of a valid contract.
- Illegal: A promise is illegal if it is for an illegal purpose.
- Void: A promise is void if it is not legally binding.
