Answer: (C)

Keeping nail products safe and long-lasting means storing them in labeled containers that are tightly closed and placed in a cool, dry place away from heat, light, and moisture, following the manufacturer’s guidelines. Labeled containers prevent mix-ups and ensure you always know exactly what’s inside; keeping the cap on protects against evaporation and contamination. Being away from heat, direct sunlight, and moisture slows chemical breakdown and helps preserve potency. Following the manufacturer’s guidelines covers the recommended temperature and humidity ranges and notes any special storage conditions or incompatibilities. Storing products next to cleaners or in unlabeled containers increases the risk of contamination or chemical reactions and makes it easy to misidentify substances. Direct sun or heat can degrade ingredients and reduce effectiveness or create safety hazards. By keeping products properly labeled, tightly closed, and stored under appropriate conditions, they stay safer and perform as intended.
