Having freckles is dominant over not having freckles, and curly hair is dominant over straight hair. One parent is homozygous for freckles and has straight hair. The other parent does not have freckles and has straight hair.

Let F represent freckles and f represent no freckles; let C represent curly hair and c represent straight hair. The first parent is FFcc, and the second is ffcc, so every child inherits F from the first parent and f from the second, giving freckles (Ff). Both parents pass on c for hair, so the children have straight hair (cc). The correct choice is B, freckles with straight hair.
