Correct Answer: Iodine

Solution : The correct option is Iodine.

Iodine comes from a variety of sources, including sea algae. Iodine may be accumulated by marine algae, often known as seaweed, from the seawater in which they grow. Iodine derived from seaweed is utilised in a variety of purposes, including nutritional supplements, medicines, and as a natural supply of iodine in food items in some situations. Certain macroalgae, particularly brown algae (Phaeophyceae), generate iodine. Laminaria, commonly referred to as kelp, is a well-known iodine-producing brown algae species.
