This declares a pointer to an integer. The * indicates that ptr is a pointer, and the int specifies the type of the variable being pointed to. Option A declares an integer variable named ptr, not a pointer. Option B makes no sense, as * must be placed before the variable name to declare a pointer. Option C uses an incorrect syntax, as the * must be placed before the variable name. Option E is incorrect as well, as the correct answer is D.
