Steganography vs concealment ciper

[Neuvin]

Hello,

My understanding of this is as follows:

"A null cipher, also known as concealment cipher, is an ancient form of encryption where the plaintext is mixed with a large amount of non-cipher material "

key terms here: NULL Cipher =>Concealment cipher.

And the questions states : "within  the text of this question"  --> within being another key term on this question.

I believe C is the right answer.

Please share what you think on this.

I do believe that this edition (8th) was written with out her and there are some annotations as to some things that have changed so, yes, I believe they are maintaining the book.

That does seem likely given that the 8th edition came out 4 years after her death and lists both Shon Harris and Fernando Maymí as authors, as did the 7th edition which was released 1 year posthumously.
