In the following question, one part of the sentence may have an error. Find out which part of the sentence has an error and click the option corresponding to it. If the sentence is free from error, click the 'No error' option. The admission of India and Pakistan has expanded (A)/ the geographical, demographic and economic profile of the SCO (B)/ which now has about half of the world's population. (C)/ No error (D)?

Option 3 : C

Correct option - 3

Here, we discuss the difference between phrase 'half the population' and 'half of the population'. When the emphasis is given on difference between two halves of something such as 'population', then we use 'half of the population'. 

For e.g. :- Half of the population is Spanish.

Whereas, when no preference of one over another, then 'half the population' is used.

For e.g. :- Half the population are eligible to vote.

Note :- In most of the cases. 'half the population' is used. So, remove of from the sentence. Thus, option 3 is the correct answer.

Correct sentence - The admission of India and Pakistan has expanded the geographical, demographic and economic profile of the SCO which now has about half the world's population.
