What is the total amount of calories per serving in a 250 ml serving of canned soup that contains 94 calories?

The total amount of calories per serving in this case is directly stated to be 94 calories for a 250 ml serving of the canned soup. Since the question asks for the total amount of calories in one serving, it is straightforward to see that the answer matches the given information.

In nutrition labeling and food measurement, a "serving" typically refers to a specified quantity of food, which in this case is 250 ml of soup. The number of calories is quantified specifically for that serving size. Therefore, if the label indicates that a serving contains 94 calories, this is the correct and complete caloric measurement for that serving.

The other choices represent either arbitrary amounts or significantly deviate from the information provided. Thus, confirming that 94 calories is the correct response logically follows from the information given on the soup's nutritional content.
