(A) Polio, although it is eradicated in the United States, it continues elsewhere and is able to be
(B) Polio, although eradicated in the United States, it still continues elsewhere and can be
(C) Although still continuing elsewhere, polio has been eradicated in the United States and could be
(D) Although having been eradicated in the United States, polio still continues elsewhere and is capable of being
(E) Although eradicated in the United States, polio continues elsewhere and could be
Nice.. I am between D and E here
I do not like "is capable of" in D.. but I have to admit, that "is capable of being" is better than "is able to be".
Having been eradicated = having been + past participle (perfect participle)
See the following extract (

Perfect Participle
The perfect participle can be used to shorten or combine clauses that have the same subject if …
… one action (the one where the perfect participle is used) is completed before the next action starts.
Example: She bought a bike and cycled home. – Having bought a bike, she cycled home.
… one action has been going on for a period of time when another action starts.
Example: He had been living there for such a long time that he didn't want to move to another town. – Having lived there for such a long time, he didn't want to move to another town.
The perfect participle can be used for active and passive voice.
active voice: having + past participle (Having cooked, he set the table.)
passive voice: having been + past participle (Having been cooked, the food looked delicious.)
Could in E seems to be odd.. We use could to point past possibility, certainty level, suggestions..
I go with D..
