Blue anti-freeze: which statement is correct?

Explanation:
Color coding in coolants is used to help distinguish base chemistries. Blue antifreeze is commonly used for propylene glycol–based formulations, so that statement aligns with typical product color conventions. The other options don’t fit as reliably: the color alone isn’t a guarantee of “long-life” chemistry, the coolant shown as blue is not colorless, and blue is not universally tied to ethylene glycol—many blue coolants are propylene glycol-based.
