Correct option is A
The correct option to fill in the blank is (a) many evil.
Explanation: The phrase "many evil practices" is grammatically correct, where "evil" is used as an adjective to describe plural countable nouns like "practices."
The determiner "many" correctly modifies plural countable nouns.
(Hindi meaning: कई बुरी प्रथाएँ)
Example: The reformer fought against many evil practices prevalent in society.
Explain why other options are incorrect:
· (b) all evil: Too absolute; not suitable in this context. (Hindi: सभी बुराइयाँ)
· (c) most evil: Indicates majority, not variety. (Hindi: अधिकांश बुराइयाँ)
· (d) more evil: Comparative form needs a second object for comparison. (Hindi: अधिक बुराइयाँ)
