What restriction is placed on a student pilot regarding carrying passengers?

A student pilot is not permitted to carry passengers. This regulation is in place to ensure the safety of both the student pilot and any passengers, as student pilots are still in the training phase and may not have the necessary experience or proficiency to handle additional responsibilities or potential emergencies that could arise when flying with passengers on board.

Carrying passengers could introduce distractions and complexities that might exceed the student pilot's current skill level. The restrictions placed on student pilots are designed to help them focus on their training and gain the experience required to operate an aircraft safely before transitioning to carrying passengers as a private pilot.

In contrast, while the other options suggest potential allowances for carrying passengers, none of them reflect the established rules governing student pilots. The regulations clearly emphasize that during training, student pilots should concentrate solely on their flight instruction without the added responsibility of passenger care.
