Correct Answer - Option 3 : Ramesh
The logic that follows here is
1) Sasi is shorter than Ramesh
Ramesh > Sasi
2) Ramesh is taller than Hari who is shorter than Sasi
Ramesh > Sasi > Hari
3) Mahesh is taller than Indrajith but shorter than Hari
Ramesh > Sasi > Hari > Mahesh > Indrajith
Therefore, the correct order is
Ramesh > Sasi > Hari > Mahesh > Indrajith
From the above order, it is clear that Ramesh is the tallest person among all.
Hence, the correct answer is Ramesh.
