Correct Answer - Option 3 : Rekha
Given,
1) Preeti scored more than Deepak.
2) Deepak scored more than Upasana.
3) Upasana scored as much as Divya.
Preeti > Deepak > Upasana = Divya
4) Manju scored less than Divya.
5) Rekha scored less than Manju.
Preeti > Deepak > Upasana = Divya > Majnu > Rekha
Clearly, Rekha scored the lowest.
