Which of the following occurs due to deficiency of vitamin K?

Correct option is A

The correct answer is (a) Failure of clotting of blood.
· Vitamin K is essential for the synthesis of certain proteins required for blood clotting (coagulation). A deficiency in vitamin K can lead to failure of blood clotting, resulting in excessive bleeding even from minor injuries.
Information Booster:
· Blood Clotting: Vitamin K is required for the synthesis of prothrombin, a key protein and clotting factor in the blood. Without sufficient vitamin K, the body's ability to form blood clots and stop bleeding is impaired.
· Sources of Vitamin K: Green leafy vegetables, such as spinach and kale, as well as other foods like broccoli, Brussels sprouts, and certain vegetable oils, are good sources of vitamin K.
· Other Conditions: The other options listed (non-maturation of ovum, neuritis, and blastocyst formation) are not related to vitamin K deficiency but are associated with deficiencies or conditions involving other vitamins or health factors.
