The correct answer is factor VIII.
Classic hemophilia or Hemophilia A, also known as factor VIII deficiency refers to a genetic disease resulting due to defective or missing factor VIII, that is, a clotting protein. Though it is inherited from parents to offspring, about one-third of the conditions arise due to a spontaneous mutation, that is, a modification in a gene.
Hence, while planning care in the given condition, the nurse should remember that the child has a deficiency of factor VIII.
