The value of the determinant ∣5_C_0 5_C_1 5_C_2 5_C_3 5_C_4 5_C_5 1 4 1 1∣ is (A) 0

To fill 12 vacancies, there are 25 candidates of which 5 are from scheduled caste. If three of the vacancies are reserved for scheduled caste candidates while the rest are open to all; the number of ways in which the selection can be made is a. ""^5C_3 xx ""^(22)C_9 b. ""^22C_9-""^5C_3 c. ""^22C_3+ ""^5C_3 d. none of these
