Solution

The correct option is A X-chromosome
In man sex linked characters are mainly transmitted through X chromosome. Father transmit the affected allele present on X-chromosome to the daughters while mother transmits it to both son and daughters. Y-chromosome is present in males only and it carries very few genes. Hence, frequency of transmission of sex linked characters through Y is very low. Option A is correct.
