How many lines will the loop in the following code read if the file 'in.txt' contains 10 lines? How many if it contains 7 lines? f = open('in.txt') line = f.readline() counter = 0 while line!= . line = f.readline() print(line) 3 f,readline() line = print(line) counter+=2 f.close() a. 9 and 6 lines, respectively. b. 10 and 7 lines, respectively. c. 2 and no lines, respectively. d. The loop is infinite, so it reads the whole file except the first line; so 9 and 6 lines, respectively. e. The file exhaustively read before the loop, so the loop does not read any lines at all.
