Option A is the only correct statement as it follows the correct syntax of the testAlpha function where it takes an integer, a character, and a double as parameters. Option B is incorrect as it includes unnecessary typecasting. Option C is also incorrect as it tries to pass string literals instead of valid data types. Option D is incorrect as it tries to pass a string literal where an integer is expected, and also tries to pass a string literal enclosed in double quotes where a character is expected.
