NEET Biology question

Assertion: In the energy conserving phase of glycolysis, the conversion of BPGA to PGA is catalysed by phosphoglycerate kinase. Reason: In the energy spending phase of glycolysis, the hexoses are phosphorylated.

(A)Both assertion and reason are true and reason is the correct explanation of assertion.
(B)Both assertion and reason are true but reason is not the correct explanation of assertion.Correct
(C)Assertion is true but reason is false.
(D)Both assertion and reason are false.

Solution

The assertion is true: phosphoglycerate kinase does catalyse 1,3-bisphosphoglycerate (BPGA) → 3-phosphoglycerate (PGA), generating ATP. The reason is also true (hexoses are indeed phosphorylated in the energy-spending/investment phase), but it
