B Correct answer
Explanation

Color blindness is a classic X-linked recessive trait - the gene is located on the X chromosome, making it sex-linked. Males (XY) express it with one affected X, while females (XX) need two affected X chromosomes. Baldness is sex-influenced (hormone-modified) rather than sex-linked. Diabetes is polygenic/multifactorial and polio is an infectious disease, neither being sex-linked genetic conditions.
