Approve to disapprove as praise is to

Interestingly, antonym of any word is the opposite annotation for the same.

Here, when we deeply analyze the first group, "approve and disapprove", we notice the use of prefix- "dis-" before the main word to alter the meaning. However, if we had to use a simple antonym in the first group, we could have quote "refuse" in the place of "disapprove."

Therefore, through my understanding, I would suggest that the correct pair for the second word, "praise", would be "dispraise" instead of "criticize".

this is not english work

explanation:

it is math
