C is irrelevant to variable memory allocation scheme and compaction. We certainly reduced memory wastage by compaction But saying 'minimal' is absurd .. So A is the correct available answer. the thing we have to know is Compaction is not a good thing to follow to reduce fragmentation because it causes high copying overhead , which is never preferable. 1 votes 1 votes Please log in or register to add a comment.
