The correct answer is: she won't have children with the disease because for this particular condition to appear, both parents need to have the trait and she doesn't have it.

Explanation:

Sickle Cell Disease is a condition that affects the red blood cells, since the hemoglobin (the protein inside the red blood cells that carry oxygen and carbon dioxide) is abnormal. This condition produces anemia and may lead to higher chances of bacterial infection and strokes.

Sickle Cell Disease is a genetic condition that is inherited in a recessive way: this means that for someone to have it, both parents must have the trait for the condition.
