C Correct answer
Explanation

In C#, the @ prefix before a string literal creates a verbatim string where backslashes are treated literally (not as escape characters). For example: @"C:\path" is interpreted as-is. The # prefix is used for preprocessor directives like #if. The . and & characters have no special meaning as string prefixes. Only @ creates verbatim strings.
