Re-arrange the jumbled parts of the sentence.
disbursement of pension expeditiously (P) all efforts are made to process the (Q)
once all requisite documents are received from (R) the beneficiaries (S)

Correct option is B

The correct sequence to rearrange the jumbled parts of the sentence is (b) RSQP. Here’s how this works:
· R (once all requisite documents are received from) provides a starting conditional clause, setting the context for when the actions in the rest of the sentence take place.
· S (the beneficiaries) follows R and completes the conditional clause, specifying from whom the documents must be received.
· Q (all efforts are made to process the) follows next as it starts the main action that takes place after the condition in RS is fulfilled.
· P (disbursement of pension expeditiously) finishes the sentence, detailing what specific efforts are being made - the expeditious processing of pension disbursement.
When arranged, the sentence reads: "Once all requisite documents are received from the beneficiaries, all efforts are made to process the disbursement of pension expeditiously."
This arrangement (RSQP) makes the sentence coherent by clearly linking the conditional receipt of documents to the subsequent efforts to expedite pension processing.
