In the Cipher Block Chaining (CBC) mode, the input to the encryption algorithm is:
A. The each plain text block encoded using same key
B. The each plain text block encoded using different key
C. The XOR of the current plain text block and the preceding cipher text block, same key used for each block
D. The XOR of the current plain text block and the preceding cipher text block, different key used for each block
