Explanation:

• The government’s flagship pro-poor scheme Pradhan Mantri Ujjwala Yojana (PMUY) has found maximum success in Delhi, Goa, Haryana, Uttarakhand and Puducherry.
• These are the states with the maximum percentage of beneficiaries who availed at least four cooking gas refills in the period between May 2016 and June 2019.
• Telangana, Chhattisgarh and Tripura were in the bottom of the list.
• Delhi topped the list of states with maximum percentage of PMUY beneficiaries availing at least four refills. Delhi had 63,894 beneficiaries at the end of December 2018. Of these, 86 per cent or 54,695 availed at least 4 refills.
• An average PMUY beneficiary in the national capital consumed 8 LPG refills in the three-year period.

Hence option 3 is correct answer.
