Correct Answer: Option C) 3 only
Silent Spring was published in 1951 - This statement is incorrect. Silent Spring, Carson's most famous work that documented the detrimental effects of pesticides on the environment, was actually published in 1962, not 1951.
Rachel Carson's work focused primarily on atmospheric pollution - This statement is incorrect. Carson's work primarily focused on marine biology, conservation, and the effects of synthetic pesticides (particularly DDT) on the environment and wildlife. Her emphasis was on chemical pollution of land and water ecosystems, not atmospheric pollution specifically.
The Sea Around Us and Under the Sea Wind are also written by Carson - This statement is correct. Rachel Carson wrote both these books as part of her sea trilogy. "Under the Sea Wind" was published in 1941 and "The Sea Around Us" was published in 1951. The third book in this trilogy was "The Edge of the Sea" (1955).
