Which option best defines flexibility (noun)?

• A. The ability or willingness to make changes
• B. Easily bent
• C. Adaptability
• D. Rigidness

Answer: (C)

Flexibility as a noun is the capacity to adjust to different conditions and to respond well to changes. The best definition among the options is adaptability, because it names the quality of being able to adjust and function across varied circumstances. It captures both the ability and willingness to modify approaches when needed, which is the heart of being flexible. The other options touch on related ideas but aren’t as precise: easily bent describes a physical trait, rigidness is the opposite of flexibility, and the broad phrase about willingness to make changes is related but not as exact a noun for the concept.
