The most likely explanation of differing sensitivities
of different bacteria to various penicillins is:
A. Differing susceptibilities of the various penicillins to β-lactamases produced by different
bacteria
B. Differing affinities of penicillin binding proteins present in different bacteria towards
various penicillins
C. Differing penetrability of various penicillins
into different bacteria
D. Differing rates of cell wall synthesis by
different bacteria
