Correct Answer: genuine

Solution : The correct choice is the second option .

Explanation:
Superficial is used to describe something that only appears to be true until examined more closely, whereas genuine is used to describe something that is true to oneself and authentic. Both of these words imply opposite meanings and, thus, are antonyms.

The meanings of the other options are as follows:

• Praiseworthy is used to describe things that are admirable and need praise.
• Trivial is something of little to no importance.
• Shallow means not deep.

Therefore, the correct answer is, genuine.
