Choose the correct variant. Her tea is very sweet. She puts ... sugar in it.

The correct answer is 'much'. Explanation: We need to choose a quantifier to describe the amount of sugar. Sugar is an uncountable noun, so we use 'much'. 'Many' is used with countable nouns, 'little' implies a very small amount, and 'few' is used with countable nouns. So, the correct sentence is: Her tea is very sweet. She puts much sugar in it.
