Answer:

Option 1: XnY

Step-by-step explanation:

X-linked recessive traits can occur in both males and females. Since its recessive it needs both XnXn in females to show up but for males who are hemizygous (XY) they only need a defective copy of Xn for the disease to show up thus option 1 is correct.

I have added a helpful illustration below where we are talking about another x-linked recessive condition in humans: hemophilia.
