• D. It helps to reduce the toxins in blood plasma.

Answer 1

The correct option is C

It helps in clotting of blood flow.

Platelets are mainly present to prevent the blood flow out of the blood vessel and in turn form clots. The normal platelet count is 150,000-350,000 per microliter of blood, but since platelets are so small, they make up just a tiny fraction of the blood volume.
