Concept:In sentence rearrangement, first identify the main clause with subject and verb. Then attach the purpose clause, object, and final modifier in a natural order.
Explanation:Start with 'Ujjwala 2.0 was launched in 2021' (Q) as it provides the subject and main verb.
Follow with 'to provide additional one crore LPG' (P) to show the purpose.
Then add 'connections to adult women of poor' (S) to complete the object and beneficiaries.
End with 'households under the Pradhan Mantri Ujjwala Yojana' (R) to specify the scheme and finish the noun phrase.
Thus the correct sequence is QPSR.
The full sentence is: 'Ujjwala 2.0 was launched in 2021 to provide additional one crore LPG connections to adult women of poor households under the Pradhan Mantri Ujjwala Yojana.'
Other options create either dangling phrases or illogical order.
Answer:Option D. QPSR
