Python Question What is the output of this code and why?

@RealBenjizo Answer: B Solution: The function is the tricky part, let's zoom in on that. The function call passes the argument d to modify_dict. But modify_dict doesn't "modify" d. Rather, it gives the name d to something else (dictionary with grandma). And, that changed d is just a +

@RealBenjizo local variable. And then we return d. But that returned value is never saved. So, the d in the main program remains unchanged.
