A. Calcium
B. Manganese
C. Phosphorus
D. Iron

Answer 1

Hint: Calcium helps binding clotting enzymes in platelets and tissue to phospholipids and accelerates reaction.

Complete step by step answer:
> Calcium plays a major part in blood clotting or blood coagulation. Increased calcium concentration in platelets helps to activate various proteins that are essential for blood clotting, resulting in a blood clot being formed.
> Calcium is a mineral which is essential for our life. Calcium causes our muscles to contract, our blood to clot and our heat to beat, in addition to strengthening bones and maintaining them healthy. Around 99% of our body’s calcium is in our bones and teeth. Body requires calcium to keep its bones healthy and perform several essential functions.
> Manganese is a mineral present in a number of foods, containing nuts, legumes, beans, tea, whole grains and leaf greens. It is treated as an important nutrient, since it allows proper functioning by the body.
> Phosphorus is an element with symbol P and atomic number 15. We found phosphorus in two forms white and red phosphorus. Phosphorus is a very reactive material thus it is never present as a free element on Earth.
> Iron is a mineral that exists naturally in many foods, is added to some foods and is used as a dietary supplement. Iron is an integral component of hemoglobin.

Hence, the correct answer is A.

Note:
Dairy foods like milk, cheese, green leafy vegetables, bread and anything made with fortified flour are the source of calcium.
