By the reference of the chart of growth rate presented by CDC,
These informations can be found-
Weight :
 A= 50% 
B=50% 
C=50-75%
Height :
D=10-25% 
E=25% 
F=25%
Then the percentage of height by weight ratio
Height by weight%:
 G=75-90% 
H=75-90% 
I=75-90%
Thus, the correct answer is -
1. Based on height he is 50% and height he is 25%
2. The nutritional needs are normal due to the constant percentage in both height and weight throughout.
