Answer» CORRECT option is (d) ^74C4 For EXPLANATION: LET assumes that there are 75 identical balls which are to be arranged in 5 different compartments (Since a, b, c, d, e are distinguishable). If the balls are arranged in the row. We have 74 GAPS where we can place a BALL in each gap since we need 5 compartments we need to place only 4 balls. We can do this in ^74C4 ways.
