Which of the following items is known for high theft in stores?

The correct answer is that spices are known for high theft in stores. This is largely due to their high value-to-weight ratio, as they can be quite expensive relative to their size, making them easy to conceal. Additionally, spices are often sold in small quantities, which makes them easier to steal without attracting much attention. Their popularity in cooking and flavoring makes them appealing to shoplifters, leading to a notable trend of theft in this category.

On the other hand, while items such as office supplies, children's toys, and greeting cards can certainly be stolen, they typically do not see the same level of theft as spices. Office supplies may have some appeal for specific individuals or settings, but they generally do not have the same urgent demand as spices. Similarly, while children's toys can be stolen, the bulk and size of many toys make them more cumbersome to conceal and steal, lowering their theft incidence. Greeting cards may experience theft, but this is often limited compared to the high demand and value associated with spices, making them less of a target overall.
