Answer:
Option B,
Explanation:
ADP consists of two phosphate group and ATP consists of three phosphate group. Thus ADP can be converted to ATP if one phosphate group is added to it.
In the process of phosphorylation, a phosphate group is added to Adenosine di phosphate (ADP) to make Adenosine tri phosphate (ATP). This process takes place inside the mitochondrial matrix during the kerb cycle process
Hence, option B is correct
