Who must accompany a learner driver in the front seat when practicing driving?

Answer: B — licensed adult

A licensed adult must accompany a learner driver in the front seat during practice driving sessions. This requirement ensures that the individual seated beside the learner is capable of providing guidance and support while they practice operating a vehicle. A licensed adult possesses the necessary experience and understanding of driving rules and regulations, which is crucial for assessing the learner's skills, offering constructive feedback, and ensuring compliance with safety practices. While other individuals such as parents or driving instructors may serve as licensed adults, the emphasis here is on the necessity of having someone who holds a valid driver's license and is of legal age to provide assistance and supervision. This arrangement is designed to foster a safe and effective learning environment for new drivers.
