(A) =N(1sA+1sB) (B) =N(1sA1sB) (C) =N(1sA+2pB) (D) =N(1sA2pB) (E) =N(2pA+2pB) All of the following are recognized as pathways that can reduce the CO2 level in the atmosphere EXCEPT (A) dissolution in the oceans (B) photosynthesis (C) respiration (D) reduced burning of fossil fuels (E) rainfall with dissolved CO2
