@Emanuel-Centeno, you're missing a step. You start with Contract Negotiators are Lied to, so CN - >L2. The next statement is that anyone who lies practices deception, so this isn't L2 - >PD but rather L - >PD (not lied TO but lied). Then whoever has been lied to (L2) also lies (L). L2 - >L, so you've got CN - >L2 - >L - >PD. Ultimately, you reach the same conclusion, but you were missing a step.
Did you get the right answer? Either way, you should have arrived at (A).
