The deficiency of which micronutrient may result in poor blood clotting and subsequent bleeding?

Correct option is C

The correct answer is Vitamin K.
• Vitamin K is a fat-soluble vitamin that comes in two forms.
• The main type is called phylloquinone, found in green leafy vegetables like collard greens, kale, and spinach.
• The other type, menaquinones, are found in some animal foods and fermented foods.
• Menaquinones can also be produced by bacteria in the human body.
• Vitamin K helps to make various proteins that are needed for blood clotting and the building of bones.
• Prothrombin is a vitamin K-dependent protein directly involved with blood clotting.
• Osteocalcin is another protein that requires vitamin K to produce healthy bone tissue.
• Vitamin K is found throughout the body including the liver, brain, heart, pancreas, and bone.
• It is broken down very quickly and excreted in urine or stool. Because of this, it rarely reaches toxic levels in the body even with high intakes, as may sometimes occur with other fat-soluble vitamins.
