Which correctly explains the difference between the terms "calorie" and "Calorie"?

In nutrition, a capital-C Calorie equals 1,000 small calories. This larger unit is also called a kilocalorie (kcal), since “kilo-” means 1,000. Therefore, the choice stating that a Calorie is made up of 1,000 calories and is also called a kilocalorie is correct.
