    Option c. 4686 kJ

    Actually b and c, are the same.

    Explanation:

    This question requires a conversion of units:

    1.12 millon calories = 1.12*10⁶ cal

    1 cal = 4.187 J → 1 cal = 4.18*10⁻³ kJ

    To make the conversion = 1.12*10⁶ cal. 4.18*10⁻³ kJ / 1 cal = 4689.4 kJ

    ≅ 4686 kJ
