A sailor who landed on the island asked A, "Are you a gentleman or a liar?" A answered but the sailor did not hear clearly what A said.

consider C is L =>B is G => A said "i am a liar" this is impossible since if A is a liar then he told the truth and if A is a gentleman then he just lied so the only other case is that C is G => B is L => A did not say "i am a liar"

yes 3 is correct... but what about statement 1 ? i think it is also correct because A can be either a liar or a gentleman

I agree with hoblos; Because B is a liar, a statement made by B against A cannot be taken as proof for whether A is a liar or a gentleman.

but if B lied and A did not say "i am a liar" and still answered the sailors question A must be a gentleman

if b is a liar then it is impossible to determine A i believe..so that means b is a gentleman..but if he is then A said he was lying..which would be impossible as well because like you said liars wont admit that and gentlemen wont say that

From the problem its difficult to find the validity of both b's and c's statement. So I'll go with the 1st.
