B Correct answer
Explanation

In ABAP, CHANGING VALUE implements pass-by-value-and-result. The formal parameter gets its own memory space (a is true), the address is NOT passed (b is false - that's reference), and at the end, the formal parameter's value IS copied back to the actual parameter's space (c is true, d is false). Therefore a&c is correct.
