Answer
A
chemical energy right arrow chemical energy
B
chemical energy right arrow mechanical energy
C
mechanical energy right arrow mechanical energy
D
light energy right arrow chemical energy

Explanation

During the light-independent reactions, the plant uses chemical energy stored in ATP and NADPH to build sugars. Because the energy starts in chemical molecules and is stored in other chemical molecules, the conversion is chemical energy to chemical energy.
