2. Axial skeleton
Explanation:

Is this just a random question or is there any information given to us about his parents? if not, C would be your answer

This means that all the offsprings of the filial 1 (one) generation will carry a recessive allele. However, those with an equivalent dominant allele will not exhibit the attached earlobe trait. This is shown by the Punnet square below;
