A Bacterial Cell That Is Resistant to a Particular Antibiotic

A bacterial cell that is resistant to a particular antibiotic may spend a large amount of energy producing the modified proteins that are needed for resistance.In such a case,what would be the effect on this cell's fitness if no antibiotic was present?

A) Its fitness would be the same as other strains that lack resistance because no antibiotics affect any of them.
B) Its fitness would be higher than other strains that lack resistance because it is prepared for a future change in the environment.
C) Its fitness would be lower than other strains that lack resistance because it is spending energy that the resistant strains can use for other purposes,such as reproduction.
D) Its fitness would be higher than other strains that lack resistance because it has more available energy to use.
E) Its fitness would be the same as other strains that lack resistance because bacteria have access to so much energy in the environment that it is not an issue in their fitness.
