Correct answer: (a) 1, 2, 3, 4
Explanation
- A
1, 2, 3, 4
1, 2, 3, 4. Integrated Rural Development Programme (1978) precedes Swarnajayanti Gram Swarozgar Yojana (1999), followed by National Rural Employment Guarantee Act (2005) and Pradhan Mantri Jan-Dhan Yojana (2014). This option correctly arranges all four government schemes in strict chronological order from earliest to latest, making it the right key.
- B
3, 4, 1, 2
3, 4, 1, 2. This option starts with the National Rural Employment Guarantee Act of 2005, which is incorrect because several listed schemes were launched much earlier. Thus, it fails to follow the correct chronological sequence.
- C
2, 3, 4, 1
2, 3, 4, 1. This sequence places Swarnajayanti Gram Swarozgar Yojana (1999) first, ignoring the Integrated Rural Development Programme which began earlier in 1978. Therefore, this option is chronologically flawed.
- D
4, 3, 1, 2
4, 3, 1, 2. This option opens with Pradhan Mantri Jan-Dhan Yojana (2014), which is the most recent scheme among the four rather than the earliest. Consequently, this arrangement is entirely incorrect.
Summary. Official key is (a) because it lists the chronological sequence as 1, 2, 3, 4 based on launch years. Integrated Rural Development Programme started in 1978, Swarnajayanti Gram Swarozgar Yojana in 1999, National Rural Employment Guarantee Act in 2005, and Pradhan Mantri Jan-Dhan Yojana in 2014. Aspirants often confuse the launch years of IRDP and SGSY. Careful validation of the exact initiation years eliminates all other chronological arrangements.
