Answer:
The sentence which uses an oxymoron is:
C.) That painting is an authentic replica of the original masterpiece.

The meaning of 'authentic' is real and original, while the meaning of 'replica' is duplicate or which is not original. Hence the two words are contradictory to each other. Therefore, 'authentic replica' is an example of an oxymoron.
