Concept:Compare the given height relations and check if one person is definitely above all others.
Explanation:Ganesh is taller than Subodh but shorter than Ravi.
So,
Ravi>Ganesh>Subodh.
Tushar and Ravi have the same height.
So,
Tushar=Ravi>Ganesh>Subodh.
Aman is taller than Ganesh.
So,
Aman>Ganesh.
But this does not compare Aman with Ravi or Tushar.
Aman may be shorter than, equal to, or taller than Ravi and Tushar.
Therefore, the tallest boy cannot be uniquely identified from the given data.
Answer:Cannot be determined from the given information.
So, none of the given options is necessarily correct.
