San, I do agree with you on your example but here in this question the adverb gradually is needed to modify the instill. So we can't place gradually anywhere else in the sentence rather than just before the "instilling" or "to instill". But due to the parallelism, "instilling" will be be a perfect fit for this sentence, so we need to use "to instill" and "gradually" properly modifies "to instill".
One way to modify option C would be to re-write it as:
To speak habitually of the "truly needy" is to gradually instill the notion - here gradually is modifying the "instill" but remember GMAT avoids the SPLIT INFINITIVES. So, we have no other best option left but C.
Hope this helps.
thanks !
