Assertion (A): Thrombokinase is essential for clotting.This statement is asserting that Thrombokinase plays a crucial role in the blood clotting process.

Reason (R): It converts inactive prothrombin into active thrombin, which is required for fibrin formation.

This provides the reason for why Thrombokinase is essential. It explains that Thrombokinase's role is to convert inactive prothrombin into active thrombin. Thrombin, in turn, is necessary for the formation of fibrin, a protein that helps in blood clotting.
So, the reason (R) supports the assertion (A), making both statements true.
