(A) $(x)$ is a conjugated diene,which is more stable due to resonance.$(w)$ is an isolated diene,which is less stable than a conjugated diene.$(z)$ is a cumulated diene (allene),which is highly unstable due to steric strain and $sp$ hybridization of the central carbon.$(y)$ is cyclobutadiene,which is an antiaromatic system and is highly unstable.Therefore,the stability order is $(x) > (w) > (z) > (y)$.
