A is incorrect because 'pursue what they had not considered......' is awkward.
and also 'better control of the other infections' or 'eradication of the other infections' is awkward.

The success of the program to eradicate smallpox has stimulated experts to pursue what they had not previously considered possible -- better control, if not eradication, of the other infections such as measles and yaws.

A. what they had not previously considered possible -- better control, if not eradication, of the other infections such as
B. what they had not previously considered a possibility -- better control, if not eradication, of such infections like
C. something they had not previously considered possible -- better control, if not eradication, of such infections as
D. something not considered a previous possibility -- better control and perhaps eradication, of other infections such as
E. the possibility of what they had not previously considered possible - better control and possibly eradication of infections like

The issues:

1. The following idioms are correct:

-> Such X as Y
--> Such as X and Y
--> Such as X, Y, and Z


==> This kills the options B and E because they have wrongly used "infections like X and Y"

2. "something not considered a previous possibility" is changing the intended meaning of the sentence.

Previous possibility---is not like "previously considered possibly"

==> This kills D.

3. "of the other X such as .." is not correct. In this case the is a problem.

Besides, "to pursue + NOUN" should be the correct way. But in the option A, pursue + Clause has been used.

Answer is C.
