The answer is A. More active than lithium -hope this helps.
Answer:
more active than lithium
Explanation:
The position of potassium is in the first group, below lithium.
a) Due to is larger size, it can give electron easily as compared to lithium thus is more reactive than lithium.
b) As it belongs to first group, it has one electron in its outermost shell, so it gives this electron easily to form positive ion. Hence it does not enter reaction by taking electrons.
c) as it can give electrons easily, so it is highly electropositive element. It will form ionic compounds with non metals like iodine.
d) due to its smaller size than rubidium, it will have more attraction for its outer electron.
