You are developing a method to decrypt data that was encrypted with the Triple DES Algorithm. The method accepts the following parameters： 
The byte array to be decrypted， which is named cipherMessage 
The key， which is named key  
An initialization vector， which is named iv 
You need to decrypt the message by using the TripleDES class and place the result in a string.  Which code segment should you use？（）
