(E)but with supplementing
Grammatical construction + Verb form
The participle supplementing would normally be expected to modify the first clause, describing or extending its meaning, but the logic of this sentence demands a contrast, not an extension. Consequently; the second part of the sentence must be revised to emphasize the contrast properly. The logic of the sentence also argues against a construction that would set the two clauses and the importance of their content equal when they clearly should not be. The best solution is to have the main clause describe the primary activity, and a subordinate clause, although they supplemented, describe the supplementary activity.

B And does not convey contrast; had supplemented is the past perfect tense but the simple past is required to match were
C And does not convey contrast and should be omitted;

D Correct. Using although creates a subordinate clause in this sentence and logically links that clause with the main clause; the simple past
supplemented parallels the simple past were.
E But with is awkward and unclear; supplementing is a modifier when a contrasting clause is needed

LSW, Thanks for your reminder! I got it.
The reason that this sentence does not use "but supplimenting" is "this sentence demands a contrast, not an extension - to modify the first clause".
