Answer:
Troll 1: Knight
Troll 2: Knave
Troll 3: Knight
Step-by-step explanation:
Troll 3's statement must be true because if they can only be knights or knaves, unless all of them are knaves, at least one must be a knight. Thus, Troll 3 is a knight.
If Troll 2 is a knight, then Troll 1 is knave, but if that were the case Troll 1's statement would be true, and since knaves do not tell the truth, this assumption is incorrect.
If Troll 2 is a knave, Troll 1 is a knight and his statement can be disregarded since it is conditioned to the possibility of him being a knave.
Therefore, Trolls 1 and 3 are knights and Troll 2 is a knave.
