Step 2: Necessary Vitamin — Vitamin K is a essential cofactor for the synthesis of these clotting factors. A deficiency leads to an increase in clotting time.

Step 3: Result — Vitamin K is the key molecule that prevents delays in or helps promote efficient blood clotting. Correct option is (b).

Key Point: Newborns or people taking anticoagulants like warfarin often focus on vitamin K intake levels.
