Which value represents the calorific value of methane in the given data?

Explanation:
Calorific value is the amount of energy released when a fuel fully oxidizes, and in this dataset it’s given per mole of methane. The energy released per mole of methane is about 890 kJ, which is commonly rounded in practice to roughly 1,000 kJ/mol. That rounding to the nearest thousand matches the value shown in the data, so the calorific value of methane in this data is the 1,000 kJ/mol figure. The other numbers would correspond to different rounding or to different units (for example, per kilogram), but the data here uses kJ per mole, hence the 1,000 value.
