Answer:

s<p<q<r

Explanation:

Given

Element s displaces p from its oxide. Thus, s is more reactive that p

p reacts with cold water  but element q cannot react with cold water. Thus,

p is more reactive than q

Element q is able to react with weak or dilute acids but element r in unable to react with weak or dilute acids. Thus, q is more reactive that r

The order of four elements on the basis of their reactivity in descending order is as follows

s<p<q<r
