P: Republic Day of India is celebrated every year on 26th of January.
Q: A huge celebration event is organised annually in the national capital, New Delhi.
R: It is celebrated at the Rajpath, India Gate before the President of India.
S: A grand ceremonial parade of Indian army takes place at Rajpath to honour the Indian Flag.
Right Answer is: A
Since the passage is about the Republic Day of India, P must be the first sentence as it states the term “Republic Day of India” and the date the event is celebrated. Since only option A starts with P, PQRS is the desired sequence.
