Final answer:
A grantee who has reached the age of majority is essential.
Step-by-step explanation:
In the context of the question, a 'grantee' refers to an individual who receives a grant. The 'age of majority' is the legal age at which a person is considered an adult and gains certain rights and responsibilities. It is essential for a grantee to have reached the age of majority, as they would have the legal capacity to fulfill the obligations tied to the grant.
For example, if a university offers a scholarship grant to students who have reached the age of majority, only individuals who are legally recognized as adults would be eligible for the grant.
