New York State Notary Practice Exam

The correct choice is guardian because a guardian is an individual who is legally appointed to make decisions and provide for the care and welfare of a minor. This role includes overseeing the minor's physical, emotional, and educational needs, which makes the guardian responsible for their well-being. While an executor manages a deceased person's estate and a trustee oversees property held in trust, neither role directly pertains to the care of a minor. A custodian might have responsibilities regarding the temporary care of a minor or their property, but this role lacks the full legal authority and responsibilities inherent in guardianship. Therefore, guardian is the most accurate designation for someone legally responsible for a minor's care and control.
