Hey there!
Here is your answer:
The proper answer to this question is option B "a person can function despite a disorder".
Reason:
Functional has many definitions but the definition that is included with Health is a person that has a disease in a certain area but can still function properly in that area.
Also....
You can use it in a sentence to understand its meaning for example:
Mr. Jenkins has functional wrist pain. (meaning Mr. Jenkins can still work his wrist but I would cause some pain)
Therefore the answer is option B.
If you need anymore help feel free to ask me!
Hope this helps!
