Are Division B students expected to be able to perform cryptanalysis with the Porta Cipher even though only Division C students should be able to encrypt/decrypt them?

Division B students should only expect to see Cryptanalysis of the Porta cipher only on State/National competitions (3.h.vi) while Division C can expect to do Encrypt/Decrypt of the Porta Cipher for Regional tournaments (3.g.iv) and Cryptanalysis on State/National competitions (3.h.vi).
