2. Read the docstring for the function below. (Recall that at the end of a tuple with just one element we add a comma in order to distinguish it from an integer that happens to be in brackets.) def add_on (lst: list[tuple], ney: Any) None: "*" "Add new to the end of each tuple in lst. things =[(),(1,2),(1), add_on(things, 99) things [(99),,(1,2,99),(1,99)] things =[] add_on (things, 99) things [] things =[(),(),()] > add_on(things, 99) things [(99),,(99),,(99), Below are three possibie bodies for this function. For each, fill in the blank so that the function will satisfy the doctest examples. If this is not possible, explain why. (a) for in in range (lon(1at)) : lst[1]= (b) for item in lot: iton. (b) for item in lst: item. (c) for item in lst: item =
