Which part of the graph represents how much energy the reactants need to gain to become products?

The answer is F , F shows the amount of energy the reactants need to gain to become products .
A potential energy diagram shows the change in potential energy of a system as reactants are converted into products.
From the figure attached we can understand the Eₐ is the activation energy reactants need to get converted into products.
Now when we study the figure( potential energy Diagram) given in the question ,
The reactants are energy level shown by G
The total energy required to get converted into products is denoted by H while ,
H - G is the actual energy required which is denoted by F.
Therefore F shows the amount of energy the reactants need to gain to become products .
