the ans is y but I don't know the reason they didn't include it in the opt cos they said RAM greater than 30 and less than 40 and it atomic no is odd which is 19 and in solutn it will form unipositive

w too is 16 + 16 = 32 so w could be the answer because it more then 30 and less than 40 so I think w is the answer since y is not in the option
