If you lose the cap to a bleach bottle, you should move the contents to a glass jar or plastic bottle.

The correct response indicates that you should not move the contents of a bleach bottle to a glass jar or plastic bottle should the cap be lost. This is because transferring bleach to a different container can lead to several safety risks. Bleach is a potent chemical that can react with contaminants or other materials that could be present in a different container, potentially creating hazardous situations such as chemical reactions or leakages.

When bleach is stored in its original container, it's typically designed to handle its corrosive nature and prevents exposure to light and air, which can degrade the chemical. Additionally, if the new container is not appropriately labeled and does not have the same warning and safety information, this can pose additional risks to anyone who may come into contact with or use the chemical later on.

Thus, it is crucial to maintain the bleach in its original packaging to ensure safety and chemical stability, making the assertion that moving it is inadvisable accurate.
