D.Impaired clotting

Answer 1

Hint:Vitamin E is a fat soluble vitamin. It is a group of eight compounds out of which four are tocopherols and four are tocotrienols. Deficiency of a substance means the presence of a substance in insufficient amounts in the body. Vitamin E deficiency is very rare and if caused in some cases is not due to low amounts in diet but because of any underlying problem in digestion of fat.

Complete answer:
Vitamin E occurs naturally in various food products like nuts, seeds, leafy vegetables, mango, whole grains, and many others. It has many antioxidant qualities and helps in keeping the immune system of the body strong. Deficiency of Vitamin E in the body is caused due to some impairment in the digestion or absorption of nutrients from food. These impairments generally include diseases like liver diseases, Crohn’s diseases and rare genetic disorders. A very low fat diet can also cause deficiency of vitamin E.
 Vitamin E was first identified due to its activity as an essential source for the fertilization of eggs. Many biological features are dependent on vitamin E and it is vital for living organisms. It plays a major role in gene expression and acts as a regulator for enzymatic activity which further helps in growth of smooth muscles.
Vitamin E is also known as sex vitamin as it helps in increasing the blood and oxygen flow to genital organs and also helps to increase stamina. Thus its deficiency in the body may cause problems related to loss of sexual power and fertility.

So, the correct answer is B.
Note:
Fat soluble vitamins are hydrophobic substances. Thus, they stay in the body for long and do not leave the body unlike water soluble vitamins that must be supplied regularly as they are excreted out with water.
