The island of knights and knaves has two types of inhabitants: knights, who always tell the truth, and knaves, who always lie. as you are exploring the island of knights and knaves you encounter two people named a and b. a tells you "i am a knave, but b isn’t". b says nothing. determine the nature of a and b, if you can.

First, suppose that A is a knight. then when he says "i am a knave" he would be lying, so you have a logical failure because knights can't lie.

if A is a knave and says "I am a Knave, but B isn’t" then he would be telling a truth in the first part.

now you have two paths to tink itm as A said a truth, he can't be a knave. but if you consider the whole sentence can be splitted in two sentences.

I am a Knave wealready know that will be a truth.

but B isn’t and now, as the first sentence is true, this must be false, so the sum of both sentences is false.

so A is a knave and B is a knave.

the answer is d
