Question Statement:

You meet two inhabitants, A and B. A says: 'Either I am a Knave or B is a Knight.' What is A?

Options:

  • (A) A is a Knight and B is a Knight.
  • (B) A is a Knave and B is a Knave.
  • (C) A is a Knight and B is a Knave.
  • (D) A is a Knave and B is a Knight.

Answer Key:

A

Step-by-Step Solution & Explanation

If A were a Knave, 'A is a Knave' would be true, making the disjunction true, which a Knave cannot speak. Thus A is a Knight. Since A is a Knight, 'I am a Knave' is false, so for the disjunction to be true, 'B is a Knight' must be true. Both are Knights!
