Crypto, Please help Question 2

A) Someone else uses a product cipher, which is more than one algorithms applied one after the other, to encrypt a message. He first used Caesar Cipher and then he applied transposition. The resulting ciphertext is:

wvfuw klrha lvufa

1. First, reverse the transposition, using the blanks. Note the result.
2. Next, decrypt the code using Caesar Cipher. Note the plaintext.

B) You find a message containing some ciphertexts which represent three words: oeryltpfkqwap

By chance you also know that the sender uses simple substitution cipher with a four-letter-words of key, starts from a capital f. This gives the first plaintext to be bid. Retrieve the key and the whole plaintext of this message.

(Hint: The encoder has removed the blanks between the ciphertext)
