On an island, Knights always tell the truth and Knaves always lie. Person A says: 'I am a Knave.' What is A?
Options:
(A) Such a statement is a logical impossibility on the island.
(B) A Knight
(C) A Knave
(D) A tourist
Answer Key:
A
Step-by-Step Solution & Explanation
If A were a Knight, he would speak the truth ('I am a Knight'), not 'I am a Knave'. If A were a Knave, his statement 'I am a Knave' would be true, which a Knave cannot say. It is an impossible paradox.
