(B) The potential energy curve for the $H_2$ molecule represents the variation of potential energy with respect to the internuclear distance between the two hydrogen atoms.At very large distances,the potential energy is zero.As the atoms approach each other,the attractive forces dominate,and the potential energy decreases.At a specific distance (the equilibrium bond length),the potential energy reaches a minimum,which corresponds to the most stable state of the molecule.If the atoms are brought even closer,the repulsive forces between the nuclei become dominant,causing the potential energy to increase sharply.This characteristic shape,showing a minimum,is represented by the graph in option $B$.

The potential energy curve for the $H_2$ molecule as a function of internuclear distance is:
