C Correct answer
Explanation

An oil filter should only be hand-tightened to prevent over-tightening, which can damage the O-ring seal or make the filter extremely difficult to remove during the next oil change. An oil filter wrench is designed specifically for removing old filters, not for installing new ones. The other options represent correct procedures for an oil change.
