Answer:
<h2>C. ADP converts to ATP.</h2>
Explanation:
The light independent process is called The Calvin Cycle, which depends on ATP and NADPH, both products of the light dependent process. So, in this process ADP doesn't covert into ATP, because during this stage is at the contrary, ATP coverts to ADP.
So, basically, after the light reactions, its products ATP and NADPH begin a new process The Calvin Cycle, here is involved 3-PGA, CO2, RuBP, G3P, giving as result Sugar, ADP, and NADP+, which goes again to the light dependent process.
