Among the given options above, the correct answer for this question would be option C. SP, SO, SM, PS, PO, PM, OS, OP, OM, MS, MP, MO. This is the only option that members of N are being listed, although with repetition, but the proper order is being observed. Hope that this answer helps.

Answer:  The answer is (C).  SP, SO, SM, PS, PO, PM, OS, OP, OM, MS, MP, MO.

Step-by-step explanation:  The given set is N = {S, P, O, M}.

We are to list the ways in which we can select two different members of N with repetition allowed and the order in which we select the members is important.

Since we are to select different members, so the cases SS, PP, OO and MM will not be considered.

The required ways will be

SP, SO, SM, PS, PO, PM, OS, OP, OM, MS, MP, MO.

Thus, the correct option is (C).
