Question 5 (1 point) In which of the following scenarios would you always need to store all lines of the file until you've read in the whole file? (where "all lines" we mean "all but one or two, possibly") a) Suppose x is given as separate input. For each line of the file, output the line if it is a multiple of x that occurs (strictly) after the last multiple of x. b) For each line of the file, output every vth line, where v is the value of the last line of the file. c) Suppose x>1 is given as separate input. Output the list created from the original file by treating the original file as a list, then using the last x values of the list as instructions for how to modify the list to produce the output. d) None of the above
