Concept:Identify the correct logical sequence of sentence parts to form a coherent statement.
Explanation:The sentence should begin with the condition that must be met first.
Part (R) “once all requisite documents are received from” introduces this condition.
Part (S) “the beneficiaries” completes the condition phrase.
So the opening is (R) followed by (S).
After the condition, the next action is stated: (Q) “all efforts are made to process the”.
Finally, (P) “disbursement of pension expeditiously” specifies what is being processed, ending the sentence.
Thus the correct order is R → S → Q → P, i.e., RSQP.
Option A (QPSR) begins with the action before the condition, which is illogical.
Option C (PRSQ) starts with the final object, disrupting the flow.
Option D (SPQR) starts with only “the beneficiaries” without the connecting phrase, making the sentence incomplete.
Answer:Option B (RSQP)
