Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
The conversion of 1,3-bisphosphoglycerate (BPGA) to 3- phosphoglyceric acid (PGA) is an energy yielding step. One of the two phosphate s of bisphoglycerate in linked by high energy bond. It can synthesise ATP and form 3- phosphoglycerate. The enzyme is phosphoglycerate kinase. The direct synthesis of ATP from metabolities is called substrate level phosphorylation.3-phospholycerate
1,3-bisphosphoglycerate +ADP $p h o s p h o g l y c e r a t e k i n a s e ⇌ + M g^{2 +}$ 3-phosphoglycerate +ATP
