The red blood cells of type AB blood have on their surfaces:

A lacteal is a lymphatic capillary that absorbs dietary fats in the villi of the small intestines.

The lacteals merge to form larger lymphatic vessels that transport chyle (a milky fluid containing fat and lymph) to the thoracic duct where it is emptied into the bloodstream at the subclavian vein.

Choice A is wrong because it is the opposite of the true statement.

Lacteals are not false, they are real structures that play an important role in fat absorption and transport.

This is because fibrinogen is a soluble protein in the blood plasma that is converted to insoluble fibrin strands by the enzyme thrombin during blood clotting. Fibrin forms a mesh-like network that traps platelets and other blood cells to form a clot.
Choice A is wrong because thrombin is not converted to prothrombin, but rather prothrombin is converted to thrombin by another enzyme called prothrombinase.
Choice C is wrong because vitamin K is not converted to prothrombin, but rather vitamin K is required for the synthesis of prothrombin and other clotting factors in the liver.
Choice D is wrong because fibrin is not converted to fibrinogen, but rather fibrinogen is converted to fibrin as explained above.
Normal ranges of fibrinogen in the blood are 200 to 400 mg/dL.

Normal ranges of prothrombin time (a measure of how long it takes blood to clot) are 11 to
13.5 seconds.
