Answer

Answer:

B. sulfur (S)

Brief Explanations:

Reactivity of non - metals generally decreases down a group and increases across a period. Oxygen is in Group 16, sulfur is also in Group 16 below oxygen, chlorine is in Group 17, and fluorine is in Group 17 above chlorine. Fluorine is the most reactive non - metal. Chlorine is also very reactive. Oxygen is more reactive than sulfur as sulfur has a larger atomic size and its outermost electrons are less strongly held, making it less reactive among these options.
