1.  pain

A. cut
B. burn
C. nuisance
D. hurt

Answer: Option D

Explanation:

Pain is suffering or hurt, so choice d is the essential element. Without hurt, there is no pain. A cut (choice a) or a burn (choice b) may cause pain, but so do many other types of injury. A nuisance (choice c) is an annoyance that may or may not cause pain.
