A Correct answer
Explanation

The syntax char *a = new char[20]; is the correct way to dynamically allocate an array of 20 characters. Option B is incorrect because 'char a' declares a single char, not a pointer. Option C is incorrect because it uses parentheses (20.0) instead of brackets [20] for array allocation.
