Answer is Wrong!
Answer is Right!
The correct answer is C. constant.
Fickle means changeable, especially in one’s affections or loyalties. The opposite
of fickle is constant, which means unchanging or reliable.A diseased person is ill, while a fast person is quick. A quick person is
able to move or act quickly, while a fast person is able to travel or perform a task quickly.Therefore, the only option that is the opposite of fickle is constant.
