Answer:
В, С, А
Explanation:
The process of clotting is known as the hemostasis which takes place in three steps: the vascular spasm, the formation of a plug of platelets and the coagulation.
In the given question, step B shows the process of vascular spasm in which the vascular blood vessels becomes constricted due to injury. After this, the platelets present in the blood starts accumulating at the site of injury. These platelets stick together and form a plug-like structure at the site of injury.

Thus, the selected option is the correct answer.
