Concept:An antonym is a word that has the opposite meaning of the given word. Since "deplore" expresses strong disapproval, its antonym must express approval.
Explanation:The word "deplore" means to feel or express strong disapproval of something (निंदा करना).
Example: The council deplores the act of vandalism that took place in the park.
"Praise" means to express warm approval or admiration for someone or something (प्रशंसा करना).
Example: The teacher praised the student for her excellent performance in the exam.
Therefore, "deplore" and "praise" are opposite in meaning.
The other options do not fit as antonyms:
"Mourn" (शोक मनाना) means to feel deep sorrow or regret, which is not the opposite of deplore.
"Dislike" (नापसंद करना) means to feel aversion, which is similar in meaning to deplore.
"Hate" (घृणा करना) means intense dislike, which is also close in meaning to deplore.
Hence, "praise" is the correct antonym of "deplore".
Answer:Option B: Praise
