Right option is (b) False

To explain: No, haemophilia is not an autosomal recessive trait. It is X-linked recessive trait and shows transmission from normal carrier female to a male progeny. In this disease, the exposed blood of affected individuals cannot coagulate due to the presence of defective blood clotting factors.
