Year-anchor elimination:
Anchor on the scheme with the most distinctive, unmistakable year first. The Kisan Credit Card is a 1998 scheme, decades older than the other three, so it must pair with the earliest year in the list. PM-KISAN, launched in February 2019, is the most recent of the four and pairs with the corresponding 2019 entry. The Soil Health Card Scheme, from 2015, and PMFBY, associated with 2014-16, take the remaining two slots in between. Ordering all four by actual launch year, PM-KISAN 2019, Soil Health Card 2015, PMFBY 2014-16, Kisan Credit Card 1998, reproduces the pairing given in the answer key as option 2.
