The U.S. birthrate started declining after World War II until the mid-1950s, and then changed to a "baby bust" in the 1970s. This was followed by a "echo boom" in the 1980s. Therefore, both options C and D are correct. The birthrate has not remained stable over the last 65 years, so option A is incorrect.
