If the word ends in silent e, drop the e and add the suffix, unless the final e is needed to preserve the sound of the preceding consonant (as in vengeance). Type the words that both end in the suffix - ance and drop the e according to the spelling rule above.

acceptance

alliance

attendance

grievance

remembrance

repentance

resemblance

resistance

vengeance

vigilance

grievance

remembrance

resemblance

Explanation:

The question is asking us to choose the words that have dropped the final - e in order to add the suffix - ance. To do so, all we need is to think of the word without the suffix, of the way it is originally spelled. When we do that, we find that the words that had - e and dropped it are:

grieve - grievance

remember (also "remembrer" in Old French) - remembrance

resemble - resemblance

The rest of the words did not have an - e originally - for instance, accept - acceptance-, or did not drop it (vengeance).
