What describes how CTR mode encryption functions?

Uses a self$-$synchronizing stream cipher where the initialization vector $($IV$)$ is encrypted and XORed with the data stream one bit at a time

Encrypts each block with the same key, where each block is independent of the others

Converts the block cipher into a stream cipher, then uses another value and a nonce to encrypt the data

Uses an initialization vector $($IV$)$ to encrypt the first block, then uses the result of the encryption to encrypt the next block
