Ans- Option (A), (B), (C).
Explanation: (A) and (B) are correct because this method returns a string that contains str1 concatenated to the end of str0. 

Now, look at another form of Concat(), which concatenates three strings:
public static string Concat(string str0, string str1, string str2). 

Hence, any number of strings can be concatenated using this method. So option(C) is also correct.
