Complete the blank using the most appropriate determiner from the options given below:
We couldn't do ___ shopping as the shops were being forcibly shut down by the police.

Correct option is C

The correct option is (c) much.

Explanation:
The word shopping is an uncountable (mass) noun. In English, determiners used with uncountable nouns in negative sentences include much. The sentence is negative (couldn't do), so much is the most appropriate determiner here.

Grammatical Rule (English):

• Much is used with uncountable nouns in negative sentences and questions. (e.g., We couldn't do much shopping.)
• Many and few are used with countable nouns.
• Lots of is used in affirmative sentences, not in negative sentences with the meaning implied here.

• (a) Few – Used with countable plural nouns (e.g., few books); not suitable with shopping.
• (b) Lots of – Generally used in affirmative contexts; awkward in negative sentences.
• (d) Many – Used with countable plural nouns (e.g., many items); not suitable with uncountable shopping.
