In the following question, out of the four alternatives, select the alternative which will improve the bracketed part of the sentence. In case no improvement is needed, select "no improvement". India is the (world's large producer) of milk, contributing about 19% of the world's total milk production with over 150 million tonnes of milk production every year.?

Option 2 : world's largest producer

The correct answer is option 2, i.e. world's largest producer.

In the bracketed part, large must be replaced with largest to highlight the degree of the comparison that India is the largest producer of milk.

In the options ‘worlds’ is incorrect as we are referring to only one world, thus, ‘worlds’ is grammatically incorrect and must be used as ‘world’s’. Only option 2 captures the grammatically correct version of the bracketed part thus, it is the most appropriate answer choice.

Hence, the sentence can be correctly rewritten as, India is the world's largest producer of milk, contributing about 19% of the world's total milk production with over 150 million tonnes of milk production every year.
