Consider the following C code segment. int a, b, c = 0; void prtFun(void); main() { static int a = 1; /* Line 1 */ prtFun(); a += 1; prtFun(); printf(“ \n %d %d ”, a, b); } void prtFun(void) { static int a = 2; /* Line 2 */ int b = 1; a += ++b; printf(“ \n %d %d ”, a, b); } What output will be generated by the given code segment if: Line 1 is replaced by auto int $a = 1$ ; Line 2 is replaced by register int $a = 2$ ;

(A)

$\begin{array}{ll} \text{3} & \text{1} \\ \text{4} & \text{1} \\ \text{4} & \text{2} \\ \end{array}$

(B)

$\begin{array}{ll} \text{4} & \text{2} \\ \text{6} & \text{1} \\ \text{6} & \text{1} \\ \end{array}$

(C)

$\begin{array}{ll} \text{4} & \text{2} \\ \text{6} & \text{2} \\ \text{2} & \text{0} \\ \end{array}$

(D)

$\begin{array}{ll} \text{4} & \text{2} \\ \text{4} & \text{2} \\ \text{2} & \text{0} \\ \end{array}$
