Solution
The correct option is B Carrier for haemophilia Haemophilia is sometimes referred to as “the royal disease,” because it affected the royal families of England, Germany, Russia and Spain in the 19th and 20th centuries. Queen Victoria of England, who ruled from 1837-1901, is believed to have been the carrier of hemophilia B, or factor IX deficiency. She passed the trait on to three of her nine children. Haemophilia was carried through various royal family members for three generations after Victoria, then disappeared.
