What is condition precedent?</h3>
- A condition precedent is an event or state of affairs that must occur before another event can occur. 
 - A condition precedent is an event that must occur before performance under a contract becomes due, that is before any contractual duty exists, according to contract law.
 - It is a provision in a will or trust that prevents the vesting of a gift or bequest until something happens or fails to happen, such as the attainment of a certain age or the death of another person. 
 - In contrast, a condition subsequent terminates a duty, whereas a condition precedent initiates a duty.
 
Therefore, this requirement is (A) a condition precedent.
