Answer:
The correct answer is flexibility.
Step-by-step explanation:
Flexibility is a characteristic of a personality that describes how far someone can deal with changing scenarios and in new, innovative form think on problems and their resolution. It usually takes place in front of stressors or events that were not expected.
