Answer and explanation
Correct answer: B. increases
Going down the group the outer electron is further from the nucleus and is lost more easily.
Answer: increases.
Why not the others: decreases: the outer electron is lost more easily down the group. stays the same: reactivity changes with atomic size. first increases then decreases: the trend is steady.
