Contour lines are used to indicate the height of the land in a map. The closer the contour lines are, the steeper the land will be, as the height of the land changes rapidly.
Therefore, if the contour lines are drawn far apart from each other, most likely the height of the land doesn't changes that much, it remains the same for a larger area, which means a plain should be the answer, as its height doesn't change as much as the other hills, cliff, or valley does.

English:
Light-dependent reactions use light energy to form two molecules necessary for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH.
Spanish:
Las reacciones dependientes de la luz usan la energía lumínica para formar dos moléculas necesarias para la siguiente etapa de la fotosíntesis: la molécula de almacenamiento de energía ATP y el portador de electrones reducido NADPH.
