Which is a manual ventilation device?

Explanation:
The main idea here is recognizing which device allows you to deliver breaths manually, not just provide oxygen. A bag-valve mask is designed for manual ventilation: it has a self-inflating bag and a mask that you squeeze to push air into the lungs, often with a reservoir so you can deliver a stronger breath and combine it with supplemental oxygen. This lets you control the rate and depth of ventilation during resuscitation or when a patient isn’t breathing adequately. The other devices are primarily oxygen-delivery tools—they passively supply oxygen at a set flow or concentration and do not let you actively deliver breaths on demand.
