Back then, CO2 levels were around 315 ppm (already an increase from preindustrial levels of about 280 ppm), but they have grown steadily, first crossing the 400 ppm threshold in May 2013.

(C) There is no theoretical maximum for the rate of photosynthesis. (D) Attempts to increase the photosynthetic yield in field crops should involve the lowering of CO2 levels. (E) Photosynthesis is unaffected by temperature.
