YOU ARE INTERVIEWING FOUR SUSPECTS IN A DRUG SMUGGLING OPERATION. THEY EACH MAKE A STATEMENT. WHICH OF THEIR STATEMENTS BELOW IS TRUE?

Well done
'C' was the correct answer!

Reason: The key is that only one statement can be true. Only suspect D’s statement can be true in isolation. If any of the other statements were true, it would have to agree with another:
If Suspect A told the truth, then so did Suspect C.
If Suspect B told the truth, then so did Suspect C.
If Suspect C told the truth, then so did either Suspect B or Suspect D.
If Suspect D told the truth, then it is possible that all the others lied. Given that we know only one statement was true, this must mean that Suspect C is the leader.
