The correct answer is A. Silent Spring.

Silent Spring is a book written by Rachel Carson and published in 1962. The book documented the detrimental effects of pesticides on the environment, particularly on birds. The book was highly influential and helped to launch the environmental movement in the United States. In 1972, the United States Environmental Protection Agency banned the use of DDT, a pesticide that Carson had identified as particularly harmful to birds.

The other options are incorrect. Option B, The environmentalism, is not a book. Option C, Biomagnification, is a process by which the concentration of a substance increases in organisms as they move up the food chain. Option D, Food chain, is a linear sequence of organisms through which nutrients and energy pass in an ecosystem.
