A girl got stuck on an island.
There are only 3 members on the island.
1 knight, 1 knave and 1 spy.
Knight always speaks truth, Knave always speaks false and spy can speaks either true or false.
Girl approaches to all three of them and get reply from all of them.

A told "I am Knight".
B told "I am Knave"
C told "B is Knight".

Then who is A?

Option:
a. Knight
b. Knave
c. Spy
d. Can't able to say.

• conditions are
  A told C is knight
  B told C is Spy
  C told B is spy
  
  according to me ...
  A must be "Knave" Because Knave satisfied the condition ..
  if A is "knave".. then it says always False .. so C is not Knight means C is "Spy"
  
  And B will be "Knight" (bcs A is Knave n C is Spy)..who always say truth "C is Spy" (condition Satisfied by first nd scnd statement)
  
  C Can speak true Or false ..so c is false that B is spy

• Answer : A is Knight
  Proof:
  According to C if "B is Knight" then B might had not lied.
  i.e. B & C both are liars.
  According to question only one person speaks true i.e. knight
  So A is Knight ..............................................................................Answer

• there are 6 conditions possible:-
  A= knight, B = knave, C = spy
  A= knight, B = spy, C = knave
  B= knight, A= knave, C = spy
  B= knight, A= spy, C = Knave
  C= knight, A= knave, C = spy
  C= knight, A= SPy, C = Knave
  
  now check the conditions for each of them being true or false,
  we will get only condition left as
  A = knight, B = Spy C = Knave

• To speak the truth person has to be knight. therefore B being the knight rules out also since c says b is knight then automatically rules out that the fact that he is saying the truth so A is knight. Also now to determine which is knave and spy:
  since B tells I am knave and knave always lies so B is a spy and which automatically makes as Knave.
