c) Hypovolemic shock

Explanation:

Hypovolemic shock occurs when circulating blood volume is reduced due to blood loss. This blood loss can occur due to hemorrhage or loss of fluid that accompanies diarrhea, burns or vomiting. When circulating blood volume is reduced, vascular pressure is reduced and tissues do not get enough oxygen and vital nutrients (tissue hypoperfusion). As a result organ systems can fail leading to death.

Peripheral vasoconstriction and movement of fluid into plasma can increase vascular pressure and restore blood flow to critical tissues like brain, kidney and heart. Approximately 10% blood volume less can occur without reducing the vascular pressure. However if 35 to 45% of blood volume is lost, sufficient supply and pressure cant be maintained.
