Hint: Seaweed are marine algae that reside underwater. Seaweed is rich in iodine and acts as a rich source of iodine.
Complete Step by Step Answer:
Seaweed are the marine algae that reside underwater in the sea, lake, river etc. They are generally brown or green in colour. The sea algae are rich in vitamin, iron metal, iodine and other minerals.
The seaweed contains the halogen element iodine. It has a very high efficiency in concentrating iodine from the available sources. Thus seaweed is used to get iodine. Thus we can write that seaweed is employed as a source of manufacture of iodine or $I$ .
Thus the correct option is B.
Additional Information: Iodine is a halogen element. It has the symbol of $I$. It generally exists as a gas. It has the colour of violet blue. Iodine is generally obtained from seaweed. Starch generally acts as an indicator in titration reactions to determine the end point of a titration. Iodine gas reacts with starch, an indicator gives blue colour.
Note: Seaweeds are a rich source of iodine but it does not contain iodine as sodium iodate. Caliche is also a major source of iodine.
