B Correct answer
Explanation

If A is a boy and says 'I am a boy', he is telling the truth. If B is a girl and says 'I am a girl', she is telling the truth. Since the prompt states 'at least one lied', they cannot both be telling the truth. If they both lied, A is a girl and B is a boy.

AI explanation

To answer this question, let's analyze the statements made by the two children:

Child A: "I am a boy" - said the child A with black hair. Child B: "I am a girl" - said the child B with white hair.

If both statements were true, then Child A would indeed be a boy and Child B would be a girl. However, we are told that at least one of them lied.

If Child A is telling the truth, then Child B must be lying because they cannot both be telling the truth. But if Child B is lying about being a girl, then Child A must also be lying about being a boy because they both cannot be telling the truth.

Therefore, the correct answer is B) Both. Both Child A and Child B are lying.
