Concept:Impute means to attribute blame or fault (आरोप लगाना). Its antonym should mean to exonerate or assist.
Explanation:The word "Impute" refers to assigning something negative, like a wrongdoing, to someone.
"Support" means to give help or backing, which is the opposite of accusing.
Example: The manager imputed the delay to the workers. (मैनेजर ने कर्मचारियों पर देरी का आरोप लगाया)
Supporting someone means standing by them, not blaming them.
The other options – Energetic, Cheerful, Lively – describe moods or energy levels, not actions related to fault attribution.
Thus, the correct antonym of 'Impute' is 'Support'.
Answer:A. Support
