Answer:
D. All of these
Read Explanation:
•Iodine is a fascinating element because it doesn't exist as a free element in nature; instead, it is harvested from these three distinct, major sources:
Seaweeds : Historically, certain brown seaweeds (like kelp) were the very first commercial source of iodine. They naturally accumulate iodine from seawater in high concentrations.
Chile salt-petre mother liquors : This is one of the largest industrial sources globally. Iodine is extracted as a byproduct during the purification of nitrate ores (caliche) found in the deserts of Chile.
Various brines : Subterranean brine waters, often found deep underground alongside oil and natural gas deposits (particularly in places like Japan and the US), are rich in iodides and serve as another massive commercial source.
