The correct answer is option 'D', None of these.

Explanation:
Determiners are words used before nouns to provide information about the noun. They can indicate quantity, possession, specificity, and other qualities of the noun. In this sentence, we need a determiner to specify the quantity of people who think that modernization is another name for development.

Let's analyze each option:

a) A lot many: 'A lot many' is not a correct determiner combination. 'A lot' and 'many' both indicate a large quantity, so using them together would be redundant. Moreover, 'many' is used with countable nouns, while 'people' is a countable noun, so it is not appropriate to use 'many' here.

b) A lot of: 'A lot of' is a correct determiner combination. It indicates a large quantity and can be used with countable and uncountable nouns. However, in this sentence, 'a lot of' does not accurately reflect the idea that only a specific group of people think that modernization is another name for development.

c) A little few: 'A little few' is not a correct determiner combination. 'A little' is used with uncountable nouns to indicate a small quantity, while 'few' is used with countable nouns to indicate a small quantity. Neither of them accurately reflects the idea of a large number of people.

d) None of these: This is the correct answer. None of the given determiner options accurately reflects the idea of a large number of people. The sentence implies that there is a significant group of people who think that modernization is another name for development, so 'none of these' is the most appropriate option.

In conclusion, the correct determiner for the blank in the sentence is 'none of these'. It accurately reflects the idea of a large number of people who hold the mentioned belief.
