Concept:Rearrange the jumbled sentence parts (P, Q, R, S) into a logical and grammatically correct order.
Explanation:The subject "the exhibition committee" needs a main verb to start the predicate.
Only part S ("has been") is a verb phrase that can follow the subject.
So S must be the first part in the sequence.
After "has been", we need a present participle to continue the verb; part R ("making efforts") fits correctly.
Next, the phrase "making efforts" requires its purpose – part Q ("to make the exhibition").
Finally, part P ("attractive and useful") describes the exhibition, completing the sentence.
Thus the proper order is S → R → Q → P.
This matches option B.
Answer:Option B: S R Q P
