Q. What is the output the program?

int main()
{
	register a=80;
	auto int b;
	b=a;
	printf("%d ", a);
	printf("%d ", b);
	
	return -1;
}

• (A) Compiler error. You can not assign register value to int variable.
• (B) 80 80
• (C) 80 0. Register value can not be copied.
• (D) Compiles, but output is none.
