You are developing a method to hash data for later verification by using the MD5 algorithm. The data is passed to your method as a byte array named message. You need to compute the hash of the incoming parameter by using MD5. You also need to place the result into a byte array.
Which code segment should you use?

A.
HashAlgorithm algo = HashAlgorithm.Create(“MD5”);
byte[] hash = algo.ComputeHash(message);

B.
HashAlgorithm algo = HashAlgorithm.Create(“MD5”);
byte[] hash = BitConverter.GetBytes(algo.GetHashCode());

C.
HashAlgorithm algo;algo = HashAlgorithm.Create(message.ToString());
byte[] hash = algo.Hash;

D.
HashAlgorithm algo = HashAlgorithm.Create(“MD5”);
byte[] hash = null;
algo.TransformBlock(message, 0,
message.Length, hash, 0);
