Solution
The correct option is A Organochlorine
Organochlorines are compounds that contain carbon, chlorine, and hydrogen. Their chlorine-carbon bonds are very strong which means that they do not break down easily. They are highly insoluble in water, but are attracted to fats. Since they resist metabolism and are readily stored in fatty tissue of any animal ingesting them, they accumulate in animals in higher trophic levels. This may occur when birds eat fish that have been exposed to the contaminant. It may also affect humans if they drink milk of a dairy cow that has ingested the chemical because the chemical is excreted in its milk fat. This is called biological magnification.
