@ankita-maurya in these kind of structures if you obtain the same structure by switching 2 branches then the structure remains same
in option 2 switch CHO and H
now switch H and OH
so you get structure in option 1 by switching 2 branches
so they are the same structure...
similarly for option 3
basic concept behind this logic is that R-S configuration doesnt change
