(a) The air passage collapses
☺
Rings of cartilage are present in the throat as it helps the throat from collapsing when there is a low amount of air present. It also helps them to expand when food or water passes through it. Thus it plays an important role in supporting the throat during air blockage and helps in smooth air flow
