In This Pathway,B $\rightarrow$ C Is Coupled with ADP $\rightarrow$ ATPCategorize the Reactions as Endergonic or Exergonic

In this pathway,B $\rightarrow$ C is coupled with ADP $\rightarrow$ ATP.Categorize the reactions as endergonic or exergonic. A ? B ? C ? D ? E

A) B $\rightarrow$ C is endergonic and ADP
$\rightarrow$ ATP is exergonic.
B) ADP $\rightarrow$ ATP is endergonic and B
$\rightarrow$ C is exergonic.
C) Both B $\rightarrow$ C and ADP
$\rightarrow$ ATP are endergonic.
D) Both B $\rightarrow$ C and ADP
$\rightarrow$ ATP are exergonic.
