What is the main purpose of encrypting a file?

Answer and explanation

Correct answer: Making its contents unreadable to unauthorised persons

The governing concept is confidentiality through encryption. Encryption transforms readable information into coded text so that an unauthorised person cannot understand it without the correct key or password. It does not delete the file, rename it, or guarantee that its size becomes smaller. Compression is a different process concerned mainly with storage size. Thus, option A is correct.
