Correct Answer: genuine

Solution : The correct choice is the second option .

Authentic means something that is original and not a copy.

Genuine means something that is truly what it is said to be. Both of these words imply originality and being true to oneself, and hence are synonyms.

The meanings of the other options are as follows:

• Incredible is used to describe things that are impossible to believe.
• Dubious is used to describe something that is questionable.
• Counterfeit is used to describe things that imitate original products with the intention of passing fraudulently.
