Correct Answer is D
Explanation
(A) Fathers can pass the disorder to their sons: Incorrect because fathers pass the Y chromosome to sons, not the X.
(B) Carrier females rarely show symptoms: While carrier females often do not show symptoms due to having one unaffected X chromosome, it is not a defining feature.
(C) Equal male and female prevalence: Incorrect because X-linked recessive disorders affect males more frequently, as they only have one X chromosome.
(D) All daughters of affected males are carriers: Since males have only one X chromosome, they pass their X chromosome to all daughters, making them carriers.
