The last one.
A. kept an equal balance between the size of the fork and the size of the surrounding buildings- uhhh no the fork is larger then the buildings...
B. manipulated proportion to create a fork too small for a traditional setting- haha it is sorta right, expect it's not too small. It's too large.
C. used an appropriate proportion to create a fork that was the correct size for human use.- it's not the correct size, it's much larger.
D. manipulated proportion to create an exaggerated fork when compared to traditional size.- yes, this is correct. The fork is much larger then human size.
Hoped I helped!!
