Correct option is B
Analyzing heights:
A is taller than only two people. (means remainings are shorter than A)
_ > _ > _ > _ > A > _ >_
D is shorter than only G. (means remaining except G, are shorter than D)
G > D > _ > _ > A > _ >_
F is taller than A but shorter than B .
G > D > B > F > A > _ >_
C is shorter than E.
Arrangement:
G > D > B > F > A > E >C
Thus, one people ‘C’ is shorter than E .
