In C, both long x and int *y are 8-byte values. How can we can tell which one is which in the assembly compiled from the C?  (I.e., what is true of one but not the other?  If several answers seem correct, pick the most precise option.) A. x is stored in a register, y in memory B. x is modified using addq, y using addl C. x may be an argument to add but y won't be D. When an argument of mov, a register storing x will never be inside parentheses
