At a pH of 7.2, which compound A or B would have better affinity for the active site?

Question

Fully detailed Question:

You notice that in the active site of the esterase there is a Phe. At a pH of 7.2, which compound A or B would have better affinity for the active site? Explain your answer structurally and through the use of the kinetic data. Your answer must fit in this space and should not exceed two sentences, otherwise points will be deducted. 

Important Figures:

 Shown below are compounds that are inhibitors for an esterase and their kinetic data is also shown below.

Answer 1

B would have better affinity because based on kinetics it reduces the Km to a greater extent than does A and both are competitive inhibitors as indicated by the double reciprocal plot. Structurally B would exhibit less stearic hindrance than A.
