Some parts of a passage have been jumbled up. Select the option that gives the correct sequence.

The Simla Agreement was signed between India and Pakistan on 2 July 1972.

P. The agreement was ratified by both Parliaments

Q. It followed the Bangladesh Liberation War

R. The agreement aimed to end conflict

S. It was signed by Indira Gandhi and Zulfiqar Ali Bhutto

The correct option is (a) QPSR.

• The paragraph should first give the background event. Sentence Q states that it followed the Bangladesh Liberation War, setting the context.
• Sentence P logically follows with official validation: the agreement was ratified by both Parliaments.
• Sentence S then provides the signing detail: it was signed by the leaders of both countries.
• Sentence R concludes with the purpose: the agreement aimed to end conflict.

Why other options are incorrect:

• RSPQ starts with the aim without giving background first.
• SQPR places signing before the historical context.
• RPSQ disturbs the logical progression of background to formal steps.

So the correct answer is (a)
