Answer : Option A
Explanation :
The chemical used in voting inks is silver nitrate. Silver nitrate is preferred because it is soluble in water, and makes an inky black solution. When put on the skin, silver nitrate reacts with the salt present on it to form silver chloride that is insoluble in water, and clings to the skin, making it impossible to wash off with soap and water or even alcohol. Mysore Paints and Varnish Limited in Karnataka is only company in India authorised to produce the indelible ink.
