D is answ. var signatureAlgo = HashAlgorithm Create(hashAlgorithm);//Creates an instance of an implementation of a hash algorithm. signatureAlgo.ComputeHash(Byte[]);//Computes the hash value for the specified byte array and returns the computed hash code => Byte[]. it is similar to B but it isn't B because: signatureAlgo.GetHashCode(); // returns Int32 and we need Byte[].

B returns the hash code of the instance of the Hashing Algorithm not the byte array
