Fill in the blank with the most suitable word.
He was rewarded for his meekness _______ and understanding heart.

Correct option is C

The correct option to fill in the blank is (c) with a wise.
Explanation: The structure of the sentence requires a phrase “with a wise and understanding heart” – two coordinated adjectives modifying a singular noun. (wise = समझदार)
Example: He led the team with a wise and patient approach.
Other options and their issues:
· (a) on a wisely – "wisely" is an adverb; incorrect use.
· (b) with wiser – “wiser” is comparative; no base for comparison.
· (d) wisest – superlative form without article/noun.
