The correct answer would be "net formation by fibrin threads"
.
Hemophilia is an X-linked recessive disorder in which a person is not able to produce clotting factors VIII (hemophilia A) or IX (hemophilia B).
These clotting factors are involved in the cascade of coagulation process which takes place after the formation of a platelet plug.
These clotting factors help in the conversion of fibrinogen (soluble protein) into insoluble fibrin which stabilizes the platelet plug and ensures that the wall of the vessel can be healed properly.
