C Sharp (C#) - Strings and StringBuilder

Astring s = "";

Bstring s = null;

Cstring s = ' ';

Dstring s = new String();

Step-by-Step Solution

Solution:

Step 1: Understand empty string creation
An empty string is a string with zero characters, represented by double quotes "".
Step 2: Evaluate each option
string s = ""; correctly assigns an empty string. string s = null; assigns null, not an empty string. string s = ' '; uses single quotes which are for chars, not strings. string s = new String(); is invalid because String() constructor requires parameters.
Final Answer:
string s = ""; -> Option A
Quick Check:
Empty string = "" [OK]
