Seaweeds are important source of A. Iron B. Chlorine C. Bromine D. Iodine

Iron
Chlorine
Bromine
Iodine

The correct answer is D. Iodine.

Seaweeds are important sources of iodine, a mineral that is essential for human health. Iodine is needed for the production of thyroid hormones, which are hormones that regulate metabolism, growth, and development. Iodine deficiency can lead to a number of health problems, including goiter, hypothyroidism, and mental retardation.

Seaweeds are also good sources of other minerals, such as iron, calcium, and magnesium. They are also a good source of protein, fiber, and vitamins.

Here is a brief explanation of each option:

  • Iron is a mineral that is essential for the production of red blood cells. Iron deficiency can lead to anemia, a condition in which the body does not have enough red blood cells.
  • Chlorine is a mineral that is essential for the maintenance of fluid balance in the body. Chloride deficiency can lead to dehydration.
  • Bromine is a mineral that is found in trace amounts in the body. Bromine deficiency has not been linked to any health problems.
  • Iodine is a mineral that is essential for the production of thyroid hormones. Iodine deficiency can lead to a number of health problems, including goiter, hypothyroidism, and mental retardation.
