Question: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 = null; 
 algo.TransformBlock(message, 0, message.Length, hash, 0); 
B HashAlgorithm algo; 
 algo = HashAlgorithm.Create(message.ToString()); 
 byte[] hash = algo.Hash; 
C HashAlgorithm algo = HashAlgorithm.Create("MD5"); 
 byte[] hash = algo.ComputeHash(message); 
D HashAlgorithm algo = HashAlgorithm.Create("MD5"); 
 byte[] hash = BitConverter.GetBytes(algo.GetHashCode());

A HashAlgorithm algo = HashAlgorithm.Create("MD5"); byte[] hash = null; algo.TransformBlock(message, 0, message.Length, hash, 0);

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

C HashAlgorithm algo = HashAlgorithm.Create("MD5"); byte[] hash = algo.ComputeHash(message);

D HashAlgorithm algo = HashAlgorithm.Create("MD5"); byte[] hash = BitConverter.GetBytes(algo.GetHashCode());

A HashAlgorithm algo = HashAlgorithm.Create("MD5");
byte[] hash = null;
algo.TransformBlock(message, 0, message.Length, hash, 0);

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

C HashAlgorithm algo = HashAlgorithm.Create("MD5");
byte[] hash = algo.ComputeHash(message);

D HashAlgorithm algo = HashAlgorithm.Create("MD5");
byte[] hash = BitConverter.GetBytes(algo.GetHashCode());
