Cesium is an alkali metal known for its high ductility, meaning it can be easily stretched into wires. It is a soft metal that reacts vigorously with water and air, ruling out low reactivity. Therefore, the most accurate property of cesium from the given options is that it is ductile. ;
Cesium is most likely to have the property of being ductile, which means it can be stretched into wires. It is a soft metal and highly reactive, making the other options incorrect. Therefore, the best answer is that cesium is ductile.
