In the following question, the first and the last part of the sentence are numbered as 1 and 6. The rest of sentences is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentences and find out which combination is connect.

1. Those that have seen the Hindus
P. have naturally no more doubt
Q. of the existence of other person
R. among them in their own country
S. of their existence than own country
6. whom they have met

Option A is the correct answer.

Option A arranges the sentence parts as follows:

1. Those that have seen the Hindus 
2. P. have naturally no more doubt 
3. S. of their existence than own country 
4. Q. of the existence of other person 
5. R. among them in their own country
6. whom they have met

When we put these together, the sentence reads:

“Those that have seen the Hindus have naturally no more doubt of their existence than own country of the existence of other person among them in their own country whom they have met.”

This sentence means that people who have seen Hindus in their own country have as much certainty of their existence as they do of the existence of any other person they have met in their own country. This makes logical sense and is grammatically correct, which is why option A is the correct answer. The other options do not form a coherent sentence when arranged in the given order.
