Four metals P, Q, R, and S were tested for their reactivity patterns. The following observations were made: (i) Metal P reacts with cold water to produce hydrogen gas. (ii) Metal Q reacts with steam but not with cold water. (iii) Metal R does not react with water or steam but reacts with dilute HCl. (iv) Metal S does not react with water, steam, or dilute HCl but reacts with concentrated nitric acid. Arrange these metals in decreasing order of their reactivity.
