Hace 4 días · As total number of ways equals k(4!), thus, k(4!)=168(4!) On comparing, we get k = 168. Hence, option (B) is correct. Note: In questions involving permutation without repetition, we have to reduce the number of choices available each time. If for the first time, we have let n choices then at the second time we are left with only (n-1) choices.
