D. Electronic codebook. Sounds like the kind of mode I'd use to encrypt my secret cookie recipe.

Gotta be D. ECB. The question literally describes it as the most basic mode. Easy peasy!

ECB. Duh, it's the most basic mode, where each block is encrypted independently. No brainer!

I prefer Cipher block chaining (CBC) because it adds an extra layer of security by XORing each block of plaintext with the previous block of ciphertext before encryption.

I'd go with ECB on this one. It's the most basic, but sometimes simple is best, you know? Though I'm partial to OFB myself - there's just something satisfying about that 'output feedback' thing.

I think Electronic codebook (ECB) is not secure because identical blocks of plaintext will result in identical blocks of ciphertext.

ECB, for sure. It's the simplest and most straightforward of the encryption modes. Though I guess that's also why it's the most vulnerable to attacks. Gotta love that 'electronic codebook' vibe, though!

The most basic encryption mode is definitely ECB. I remember learning about it in class - it's like a digital version of the old-school codebook.
