Correct Option: A

According to given question,
Vasant is taller than Manohar but not as tall as Raju.
V > M But R > V.
Jayant is taller than Dutta But shorter than Manohar.
J > D But M > J.
So V > M and M > J
Then V > M > J
R > V and J > D
Then R > V > M > J >D
Descending order of the heights is as
Raju > Vasant > Manohar > Jayant > Dutta
Hence, Raju is the tallest.
