Correct option is A
The correct substitution of the highlighted words is (a) a lot of homework.
Explanation:
"Homework" is an uncountable noun, and uncountable nouns do not take a plural form. Therefore, adding "s" to make "homeworks" is incorrect.
Grammatical Rule Used:
Uncountable noun rule – Uncountable nouns (like homework, advice, luggage, information) do not take plural forms and should not be used with plural verbs or quantifiers that imply countability.
Incorrect: a lot of homeworks
Correct: a lot of homework
Correct Sentence:
"I’ve got a lot of homework this weekend."
Information-booster:
Uncountable nouns are quantified using expressions like:
- A lot of homework
- Some advice
- Much information
Avoid using articles like "a/an" or adding -s to them.
