In this case only C must be true.

We have to put S 4th.

------ / ------- / ------ / ---S---

Since S is in, we have to kick O out. (if O goes in S can't)

Then we know H/T are both in but not next to each other. H/T have to go in slot 1 and 3. H can go 1 or 3 and T can go 1 or 3. We do this so they are not next to each other.

--h or t--- / ------ / --h or t-- / --s--

Since h or t has to go 3rd then J is out. This leaves M as our only letter to separate h and t. So M must go 2nd.

which other answer do you see as correct?

We saw letter B as the correct answer because J has to be 3rd.
