A Correct answer
Explanation

x (without quotes) refers to a variable named x, which is a named storage location in memory. 'x' (with single quotes) is a character constant representing the character 'x'. In C++, single quotes denote character constants while unquoted names are identifiers/variables. Option B is wrong because string literals use double quotes ("x"), and option D is incorrect because 'x' is a character constant, not a pointer.
