\[similarity\ concepts\ says\ that \ two \ figures\ are\ similar\\ if \ the\ ratio\ of \ their\ corresponding\ sides\ are\ equal\ (constant).\\in\ the\ given \ fiqures \ only\ last \ statemet\ satisfy \ this \ condition.\\here,\ \frac{ SR }{ ML}=\frac{ 9-5 }{ 6-4}=\frac{ 4 }{ 2 }=\frac{ 2 }{ 1}\\ \frac{ PQ }{ JK }=\frac{ 9-5 }{ 6-4}=\frac{ 4 }{ 2 }=\frac{ 2 }{ 1 }\\ so\ last\ statement \ is\ correct!\]
