10. Suppose that you want to obtain the following sum 21+41+81+161+2n1 for some positive number n and that you created the following Python function: What would you change in the function to make the calculation correct? (A)I wouldn't change a thing since the function is already correct. (B) I would change the range such that it goes up to n. instead of n+1. (C) I would replace x=I/(2i) with x=x+1/(2i). (D) I would replace x=0 with x=1. 10.
