Solution

The correct option is A Father to son
Father is heterozygotic in human and carries two types of sex chromosomes namely, X- and Y-chromosomes. The Y-chromosome of father is transmitted to his sons while the X-chromosomes is delivered to the daughters. Therefore, all Y linked genes, irrespective of recessive or dominant ones, are transferred from father to his sons only. Option A is correct answer.
