A bacterial species will inevitably develop greater resistance within a few years to any antibiotics used against it, unless those antibiotics eliminate that species completely. However, no single antibiotic now on the market is powerful enough to eliminate bacterial species X completely.
Which one of the following is most strongly supported by the statements above?
(A) It is unlikely that any antibiotic can be developed that will completely eliminate bacterial species X.
(B) If any antibiotic now on the market is used against bacterial species X, that species will develop greater resistance to it within a few years.
(C) The only way of completely eliminating bacterial species X is by a combination of two or more antibiotics now on the market.
(D) Bacterial species X will inevitably become more virulent in the course of time.
(E) Bacterial species X is more resistant to at least some antibiotics that have been used against it than it was before those antibiotics were used against it.

Bacterial species will develop resistance to any antibiotic used against it until and unless the antibiotic eliminates it completely.
No single antibiotic currently available is powerful enough to eliminate bacteria X completely.
We are looking for an inference - no new information should be added.
(A) It is unlikely that any antibiotic can be developed that will completely eliminate bacterial species X.
Nothing can be said about the future. We are only talking about the current situation.
(B) If any antibiotic now on the market is used against bacterial species X, that species will develop greater resistance to it within a few years.
Correct. No single antibiotic is strong enough to eliminate bacteria X completely. So if any antibiotic (we are talking about a single antibiotic) is used against bacteria X, it will not eliminate bacteria X completely. So bacteria X will develop resistance to it.
(C) The only way of completely eliminating bacterial species X is by a combination of two or more antibiotics now on the market.
We don't know this. We know that no antibiotic can do this job alone. Can a combination do it, we don't know.
(D) Bacterial species X will inevitably become more virulent in the course of time.
Not necessary. Perhaps, a combination of current antibiotics will eliminate it completely.
(E) Bacterial species X is more resistant to at least some antibiotics that have been used against it than it was before those antibiotics were used against it.
We don't know what happened in the past. Perhaps bacteria X is a new discovery.

Easy B.
In A, the argument doesn't mention any antibiotic that will be developed in the future, just those on the market.
Other choices are clearly irrelevant.
