Which type of passenger can ascend and descend steps while making their way to or from their cabin seat?

The correct answer focuses on the abilities of different passengers concerning their mobility. A passenger in a wheelchair for ramp assistance may need support for navigating through the terminal or boarding the aircraft but is not required to manage navigating steps independently, which shows that they depend on assistance during their travel process.

In contrast, individuals who use crutches, have permanent leg injuries, or use a leg brace may possess varying degrees of mobility, which could allow them to ascend and descend steps to reach their cabin seat without assistance. For example, a passenger with crutches or a leg brace might be able to manage steps independently, while someone with a wheelchair relies on assistance and does not typically navigate steps on their own.
