D Correct answer
Explanation

This is a logic puzzle about three brothers: John (always truthful), Jack (always lies), Joe (random). Left says 'He is John' - if left were John, he'd tell truth, making middle John (impossible). So left is NOT John. Middle says 'I am Joe' - if middle were John (truth-teller), he'd say 'I am John', so middle is NOT John. Therefore John must be on right. Right (truthful John) says 'He is Jack', so middle is Jack. Left must be Joe. This matches option D.

AI explanation

To solve this question, let's analyze the answers given by each person and determine who is who:

  1. The person sitting on the left said that the person in the middle is John.
  2. The person sitting in the middle said that his name is Joe.
  3. The person sitting on the right said that the person in the middle is Jack.

Let's analyze each option to see which one matches the given answers:

Option A) Jack on the right. The middle one is John. Joe on the left - According to this option, the person sitting on the left is Joe, but the person sitting in the middle is John. However, the person sitting on the left said that the person in the middle is John, so this option is incorrect.
