Correct answer: (C) i-c, ii-b, iii-d, iv-a

Explanation

Data lost to a hard disk crash is restored from back-up files kept as spare copies.

Self-replicating software that causes data loss is countered by anti-virus software.

Reading of illegally accessed documents is guarded against by encryption, which scrambles the content.

Software that secretly records every key press is caught and removed by anti-spyware software.

Each threat is met by the protection built to address that specific danger.

Regular back-ups and up-to-date anti-virus together cover both loss and infection.
