Solution
The correct option is B SA-node - Pacemaker
- Hemophilia is an X-linked recessive disorder and is characterized by impaired ability or inability of blood clotting which causes heavy blood loss even in the case of small injury.
- Pacemaker serves to produce rhythmic impulses for a heartbeat. The sinoatrial node (SA) node serves as a pacemaker.
- Malleus is one of the ear ossicles. Its shape resembles a hammer.
- Leucocytes refer to white blood cells and lymphocytes are just a type of leucocyte. That means all leukocytes are not lymphocytes.
So the correct answer is option B.
