The sampling frame is the list of all the individual units from which the sample is drawn. In this case, the sampling frame consists of the 10 boxes of fiber-optic Ethernet cables. However, since the manager chooses only one box at random, the sampling frame is reduced to that one box. Therefore, the best choice is B, which represents the one box of 20 cables chosen at random from the 10 boxes.
