Explanation

A Concealment cipher is a technique where a hidden message is embedded within an innocuous-looking text by selecting specific words at regular intervals (e.g., every 5th word). Option A describes a Transposition cipher. Option C describes a Substitution cipher. Option D describes Steganography, which hides the existence of data entirely. The Concealment cipher is distinct in that the cover text is readable and meaningful, but the real message is extracted by reading every Nth word or character.
