Answer:

B. shaded square

Explanation:

In pedigree analysis, squares represent the males while circles represent the female individuals. Since the horse breeder wants to show the male horse who is affected by the target gene, he should represent it with a shaded square. A shaded square in pedigree represents the affected males. Unshaded squares would represent the unaffected normal males.
