{'ascorbic acid': [3, 0, 2, 0], 'citric acid': [0, 0, 1, 0], 'good substitution': [0, 0, 2, 0], 'nutrition': [6, 0, 6, 3], 'soft drinks': [0, 1, 0, 0], 'coffee': [1, 0, 1, 0]}

The question requires identification of the correct statements among the provided options.

Statement I - Caffeine, commonly found in tea and coffee, has diuretic properties. It`s not called `caffenic`, but the concept here is correct.

Statement II - Citric acid is in fact commonly used in soft drinks, aiding in providing a tangy flavor and acting as a preservative.

Statement III - Ascorbic acid, also known as Vitamin C, plays a crucial role in the formation and maintenance of connective tissue, including bones and teeth.

Statement IV - Citric acid can`t substitute for ascorbic acid nutritionally. Although they are both acids, ascorbic acid has specific nutritional contributions that citric acid doesn`t provide.

Given these dissections, options I, II and III are correct but IV is not, leading to the correct answer being option 2, `I, II and III only`.
