Diagonal Relationship

JEE Main asked Diagonal Relationship 4 times in 4 of the 108 shifts Lumi analysed, in 2017, 2020 and 2022. It belongs to The s-Block Elements (Chemistry). The longest wait between two years asking it was 3 years, across 2018 and 2019, which Lumi has no shifts for. In 2020 it came in more than one shift of the same year.
