(A) The complexity of organisms increases from unicellular protists to multicellular plants/animals and then to complex vertebrates.$1$. $Opalina$ is a unicellular ciliate protist.$2$. $Vaucheria$ is a multicellular alga (though often studied in botany,in this context,it represents a simple multicellular organization compared to animals).$3$. $Lamprey$ is a primitive jawless vertebrate (Agnatha).$4$. $Seahorse$ is a complex bony fish (Osteichthyes).Therefore,the correct ascending order of complexity is $Opalina < Vaucheria < Lamprey < Seahorse$.

Which of the following options represents the correct ascending order of complexity in animal body organization?
