What should be done if the hash of a downloaded file does not match the official hash?

Answer and explanation

Correct answer: Stop using the file and download it again from a trusted source

The governing concept is integrity checking before execution. A hash mismatch means the downloaded bytes differ from the official reference; this may result from corruption, an incomplete transfer, or unauthorised modification. The safest response is not to open or distribute the file, to remove or isolate it, and to obtain a fresh copy from a trusted source before checking again. Renaming cannot repair its contents, so option C is correct.
