In the list provided, the most reactive element is **B. Cs (Cesium)**.
Cesium is an alkali metal, and alkali metals are known for their high reactivity, especially with water and halogens. Among the alkali metals, cesium is one of the most reactive.
The other elements you listed—barium (Ba) is also reactive (it's an alkaline earth metal), carbon (C) is relatively unreactive compared to metals, and sulfur (S) is a nonmetal that does not react as readily as alkali metals. Thus, cesium is the most reactive element on your list.
