Vote for B.

D, E change the meaning.
C: ambiguous.

what it is supposed to do is the correct phrase.

But isn't A, B and C all violating the past subjunctive rule?

if the new boat did what it is supposed to do......., it could revolutionize transport on the 2,900-mile-long Congo River.

This should be the correct sujunctive usage.

I don't find any of the choice to be correct.

A- To be doing not idiomatic
B- Idiomatic+grammatical construction is perfect
c- It means what ? Not clear
D&E Awkward.

As nakib77 correctly pointed out , why is there no 'did' in the sentence ?

Is 'to be doing' unidiomatic??

B is correct...
In my opinion the reason the writer used "does" instead of "did", is to show a future action is relation to .."revolutionize transport".
