Directions: Click on the graph to the right and select Time Series to graph the U.S. chain-weighted Real Gross Domestic Product (RGDP) and its rate of growth. Select RGDP for the Y Axis 1 data, and RGDP percent change for the Y Axis 2 data to graph the data measured in the right-hand and the left-hand side of the vertical axes, respectively. According to the graph, O A. RGDP was exceptionally stable during the period of 1930s and 1940s. O B. U.S. RGDP has drastically declined since 1990. O C. RGDP was most volatile during the 1930s and 1940s. O D. the behavior of RGDP is exceptionally smooth and uniform during the entire 1929-2004 period
