Which object is most likely to cause choking in a child?

A small toy is indeed the object most likely to cause choking in a child due to its size and shape. Small toys can easily fit into a child's mouth, and if the toy breaks into pieces or if a child attempts to swallow it, it may obstruct their airway. Unlike other choices, such as a piece of fruit, which can often be chewed or broken down into smaller pieces before swallowing, small toys are typically solid and rigid, posing a greater choking hazard.

Additionally, the materials from which toys are made can also be hard and non-compliant, increasing the risk of choking if ingested. While fruits and bread can pose choking risks as well, especially if not cut appropriately, they are generally safer than small hard objects that can block a child's air passage. A soft pillow does not present a choking hazard at all, as it is soft and cannot easily obstruct breathing.
