How many ATP molecules could maximally be generated from one molecule of glucose, if the complete oxidation of one mole of glucose to and
yields 686 kcal and the useful chemical energy available in the high energy phosphate bond of one mole of ATP is 12 kcal?

2
One mole of ATP liberates 12 kcal of energy. So 686 kcal will be liberated by
686 / 12 = 57.1 ATP molecules.
Hence, the correct answer is option 2.
