Explanation:
Option C is INCORRECT (and thus the right answer for this question) because overwriting a Delta table DOES log logical deletions of the old files and adds new files to the transaction log, eventually physically deleting them after a VACUUM. Options A, B, and D are true statements and are actual benefits of overwriting rather than dropping and recreating a table in Delta Lake.

C
Overwriting is more efficient because it doesn't delete any files.
