Decrypt means

• A. to hide information so its meaning is unreadable
• B. to delete information
• C. to change information so that its hidden meaning is shown
• D. to compress data

Answer: (C)

Decrypt means converting encrypted data back into readable form. When information is encrypted, its meaning is hidden by scrambling it with a code. Decryption uses a key or algorithm to reverse the scrambling and reveal the original message. So the act described is about making the hidden meaning visible again. It is not about hiding information, deleting data, or compressing data.
