Solution

The correct option is A Recessive trait
Some people have their ear lobes attached to the side of the head and some people have free ear lobes. This is due to a gene that is dominant for unattached earlobes and recessive in the case of attached earlobes. So, attached ear lobes are recessive in humans. Thus, the correct answer is option A.
