Final answer:
The lower the number on a label, the better the ranking it represents.
Step-by-step explanation:
To make a general statement about the number ranking on a label, we should consider whether higher numbers represent a better ranking or if lower numbers signify a stronger ranking. The statement that 'the ranking is inversely proportional to the number' implies that as the number increases, the ranking worsens, suggesting that a lower number indicates a better ranking. Thus, the correct answer is: (b) The lower the number, the better the ranking.
