Concept:The task is to arrange four jumbled sentences (P, Q, R, S) to form a logical paragraph between the given first and last sentences (S1 and S6).
Explanation:S1 introduces underprivileged people and exploitation.
Sentence Q starts the sequence by giving the first example: "begar" or forced labour.
Sentence S follows with a second related example: buying and selling human beings as slaves.
Sentence R then broadens the point, stating that the marginalised are often exploited.
Sentence P concludes by saying both forms are prohibited under the Constitution of India.
This order (Q -> S -> R -> P) makes the paragraph flow smoothly into S6, which talks about forced labour in the past.
Thus, the correct sequence is QSRP.
Answer:Option A: QSRP
