The correct option is C much
Let’s examine the sentence: “He never spends ____ money.” The sentence requires a determiner that can convey the sense of quantity of money that ‘he never spends.’ Option B cannot be used as ‘some’ is used in sentences with positive meanings. In this sentence, usage of ‘never’ indicates that the sentence has negative meaning. Option D cannot be used as ‘a lot’ requires preposition ‘of’ that is missing in the option as well as sentence. Now, let’s see the difference between ‘much’ and ‘many.’ ‘Much’ is used for uncountable nouns, and ‘many’ is used for countable nouns. As ‘money’ is an uncountable noun, so ‘much’ would be used with it. Hence, Option C is the correct answer.
