"adequate amounts of vitamin d occur naturally in the diet." b. "vitamin d3 is preferred over vitamin d2."c. "vitamin d can promote bone decalcification."d. "vitamin d increases the absorption of calcium and phosphorus from the intestine."

Adequate amounts of vitamin D occur naturally in the diet.

Explanation:

The vitamins are the chemicals that are required in the diet in the small amounts. The deficiency and its excessive presence in the body can cause the disease in the individual.

Two main types of vitamin are fat soluble vitamins and water soluble vitamins. The vitamin D is the fat soluble vitamin and its deficiency can cause rickets. These vitamins must be obtained from the external source and not present naturally in the diet.

Thus, the correct answer is option (A).

d. everyone should be treated fairly.

a, b, c - sides of a triangle

a + b > c

a + c > b

b + c > a

we have a = 5m and b = 11m. substitute:

5 + 11 > c

16 > c → c < 16

5 + c > 11         subtract 5 from both sides

c > 6

11 + c > 5         subtract 11 from both sides

c > -6

c < 16 and c > 6 and c > -6

thereofre your answer is 6m < c < 16m
