Suppose a 3072 byte file in this filesystem has its directory entry stored in cluster 5, and its first cluster of data stored in cluster 7, its second in cluster 9, and its third in cluster 8. Ignoring changes to last modification timestamps, if we appended 128 bytes to this file, storing the extra data in cluster 10, then which of the following would be modified?
A. the contents of cluster 5.
B. the FAT entry for cluster 5.
C. the contents of cluster 7, 8, and/or 9.
D. the FAT entry for cluster 7.
E. the FAT entry for cluster 9.
F. the FAT entry for cluster 10.
