Answer 2

Answer:

Both (A) "0"     and      (B) "ab" + "cd"  above.

Explanation:

• The String data type is used to store character or a sequence of characters.
• Values of a String variable must be surrounded by double quotes like,

              string ch = "Hello";

• The + operator can be used between two or more strings to add them together to make a new string. This is called concatenation of Strings.
• Concatenation is the process of appending one string to the end of another string. We can  concatenate many strings by using the + operator like:

string fName = "John ";

string lName = "Doe";

string fullname = fName + lName;

• "ab" + "cd" is the concatenation of two strings "ab" and "cd".
