"Praise" involves expressing approval or admiration, while "Condemn" involves expressing strong disapproval or criticism. Therefore, option (B) Condemn is the most suitable antonym in this context.

"Conceit" refers to an excessive sense of self-importance or pride, often accompanied by an overestimation of one's abilities. The antonym, "Modesty," represents a quality of being humble, unassuming, and free from excessive pride or self-assertion. Therefore, option (C) Modesty is the opposite or antonym of "Conceit."

In the context of the sentence, "bestow" means to give or confer. The opposite or antonym of giving is denying, so option (C) deny is the most appropriate antonym.
