Correct answer: (a) 2 3 4 1
Explanation
- A
2 3 4 1
Option (a) pairs Pradhan Mantri Shram Yogi Maan-Dhan Yojana with ₹55-₹200 per month contribution, reflecting the age-dependent monthly subscription model for unorganised workers. This matching continues correctly through the remaining schemes to form the sequence 2, 3, 4, 1. Therefore, this option accurately connects all social security programmes with their respective beneficiary contributions as established by government guidelines, making it the correct key.
- B
2 4 1 3
Option (b) starts with 2 for the first scheme but incorrectly maps the subsequent scheme contributions to 4, 1, and 3. This disrupts the accurate alignment of Pradhan Mantri Jeevan Jyoti Bima Yojana and Pradhan Mantri Suraksha Bima Yojana. Consequently, this sequence fails to match the official contribution rates.
- C
1 2 3 4
Option (c) incorrectly assigns 1 as the contribution for Pradhan Mantri Shram Yogi Maan-Dhan Yojana, which actually has a fixed age-specific monthly contribution rather than pure beneficiary choice. This misplacement invalidates the entire sequence from the very first item.
- D
3 2 1 4
Option (d) begins with 3 for the first scheme, which corresponds to Pradhan Mantri Jeevan Jyoti Bima Yojana instead of Pradhan Mantri Shram Yogi Maan-Dhan Yojana. This initial error cascades through the list and breaks the correct pairing of all social security programmes.
Summary. Official key is (a) because it correctly matches each social security scheme with its precise beneficiary contribution rate. Pradhan Mantri Shram Yogi Maan-Dhan Yojana requires ₹55 to ₹200 per month based on entry age. Pradhan Mantri Jeevan Jyoti Bima Yojana entails an annual premium of ₹436, while Pradhan Mantri Suraksha Bima Yojana costs ₹20 per year. Atal Pension Yojana leaves the contribution amount to the beneficiary's choice based on the desired pension output. Thus, only option (a) presents the exact sequence of 2, 3, 4, 1.
