Correct Answer :
A. much more
The given statement refers that there will be more amendments, but that its basic structure will still remain the same. Option (b) is correct, because many more means an increase in the number. Option (a) is incorrect, because much is used in cases of uncountable nouns. Option (c) is incorrect, because too many more refers to a huge number of amendments, and we have already explained that its not what the statement refers to. Option (d) is incorrect, because quite refers to the degree or intensity, so it is saying that there will be very few more amendments, which is not what the author intends.
