Which of the following foods should not be served due to choking hazards?

Raisins are considered a choking hazard, especially for young children. Their small size and chewy texture can make them easy to swallow whole without adequate chewing, increasing the risk of choking. When serving snacks to young children, it's important to choose foods that are easy to chew and swallow. Soft fruits, mashed potatoes, and fruit smoothies are generally safe as these options are softer in texture and can be consumed more easily, minimizing the risk of choking. It's crucial to be aware of the specific characteristics of certain foods, particularly regarding how they can pose a risk in the context of children's eating habits.
