Two charges q1=−17C and q2=6C are positioned at different coordinates as shown in the figure. Coordinate of q1 charge is (b, a) and that of q2 charge is (−b, a) . Find the net electric field at the origin in unit vector notation . Assume that a=2m and b=7m . Here C denotes coulombs and m denotes meters.

Then the answer would be d then

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
