What items should be included in the bus's first aid kit?

The correct choice consists of essential first aid items that are crucial in responding to medical emergencies. Band-aids, antiseptic wipes, and gauze are fundamental supplies for treating minor injuries, such as cuts and scrapes, promptly and effectively. These items help to clean wounds, prevent infection, and promote healing, making them critical for any first aid kit.

Additionally, including emergency contact information ensures that in the event of a serious injury or medical emergency, help can be alerted quickly and efficiently. Knowing who to contact and having their information readily available is vital for the safety and well-being of everyone on the bus.

Other choices, while they may contain useful items, do not focus on the primary purpose of a first aid kit, which is to provide immediate medical assistance in case of injury or health issues.
