Bacteria are very small organisms, usually consisting of one cell, that lack chlorophyll (a green pigment found in plants that allows for the production of food). Except for viruses, they are the smallest living things on Earth. Many bacteria are so small that a million of them, laid end-to-end, would measure no more than about five centimeters (two inches). The term bacteria is the plural form of the word bacterium, which represents a single organism. <span>

The correct answer is option B, that is, a neighborhood there had been built over a toxic dump.
In 1978, Love Canal, situated close to the Niagara Falls in the upstate New York, was a nice small working-class enclave with many houses and a school. It just occurred to have been sitting at the top of 21000 tons of toxic industrial waste, which had been buried underground in the 1940s and 50s by a local company.
The families living in the chemicals were not familiar that they were being encountered with poisonous chemicals, nor were they aware of the chemical wastes being dumped into the soil, rivers, and air. The toxic wastes influenced the lives and damaged the environment.
