They can form a part of viable encryption methods
for example - https://en.wikipedia.org/wiki/XOR_cipher
The XOR operator is extremely common as a component in more complex ciphers. By itself, using a constant repeating key, a simple XOR cipher can trivially be broken using frequency analysis. If the content of any message can be guessed or otherwise known then the key can be revealed. Its primary merit is that it is simple to implement, and that the XOR operation is computationally inexpensive. A simple repeating XOR (i.e. using the same key for xor operation on the whole data) cipher is therefore sometimes used for hiding information in cases where no particular security is required. The XOR cipher is often used in computer malware to make reverse engineering more difficult.

I can’t believe they would say binary operations are completely useless; that seems too extreme. I think they definitely have some role in encryption.

I feel like I’ve seen a question similar to this before, and I lean towards C as well, but I’m not completely confident.

I think option C sounds familiar from our practice questions, but I’m a bit hesitant about whether they can really form a viable method.

I remember we discussed how binary operations can be part of encryption algorithms, but I'm not sure if they can provide secure encryption on their own.

Binary operations? Encryption? I'm drawing a blank on how those two things are connected. This question is not clicking for me at all. I'll have to guess and hope for the best.

Hmm, I'm a bit unsure about this one. Binary operations and encryption - I know they're related, but I'm not totally clear on the specifics. I'll have to review my notes and try to reason through the options.
