Chosen-PlainText Attack:Attacker Defines his own plaintext, feed it into the cipher, adn analyzes the resulting cyphertext Ciphertext-only attack-Attack has access to the cipher text; goal of this attack is to recovery the encrypiton key from the cypher text AdaptiveChose Plaintext attack:Attacker makes a series of interactive queries, chosing subsequent text based infmraiton from the previous encryptions known-plaintext attack:attackers had knowedge of some part of the plain text; usign this informaiton, the kye used to generate ciphertext is deduced so as to decipher other messages

With chosen-plaintext attack, the attacker is allowed to choose an arbitary amount of plaintext to encrypt. ... With the adaptive-chosen-plaintext attack, he/she can do the same as with the Definetely C:chosen-plaintext attack, but is also allowed to encrypt new data after the attacker has looked and analyzed previous encrypted bits

The answer should be C I think. https://simple.wikipedia.org/wiki/Chosen-plaintext_attack#:~:text=A%20chosen%2Dplaintext%20attack%20(CPA,security%20of%20the%20encryption%20scheme.

I would say C. From Matt Walker all-in-one book: Adaptive chosen plain-text attack The EC-Council definition for this is mindnumbingly obtuse: “the attacker makes a series of interactive queries, choosing subsequent plaintexts based on the information from the previous encryptions.” What this really means is the attacker sends bunches of cipher texts to be decrypted and then uses the results of the decryptions to select different, closely related cipher texts. The idea is to gradually glean more and more information about the full target cipher text or about the key itself.

All sources I have found show that C is correct but in my v10 exam A was correct.
