The Ayushman Bharat - National Health Protection Mission (AB-NHPM), now known as Pradhan Mantri Jan Arogya Yojana (PM-JAY), was launched to provide health insurance coverage to economically weaker sections of society. It subsumed two major pre-existing health schemes:
1. Rashtriya Swasthya Bima Yojana (RSBY) - A health insurance scheme for below-poverty-line (BPL) families.
2. Senior Citizen Health Insurance Scheme (SCHIS) - A scheme providing health coverage for senior citizens.
Since both these schemes were merged into AB-NHPM, the correct answer is (D) Rashtriya Swasthya Bima Yojana (RSBY) \& Senior Citizen Health Insurance Scheme (SCHIS).
