Vedclass · Answer

(A) The Ostrich $(Struthio camelus)$ is a member of the class Aves because it possesses feathers, lays eggs, and has a beak, which are characteristic features of birds.However, it is a flightless bird due to the absence of a keel on its sternum, which is required for the attachment of large flight muscles.Both the assertion and the reason are scientifically correct statements.The reason $(R)$ explains why the Ostrich is classified as a bird despite its inability to fly, as flightlessness is a secondary adaptation in some avian species, not a disqualifier for the class Aves.Therefore, $R$ is the correct explanation for $S$.

$S -$ Assertion: Ostrich is an animal belonging to the class Aves.
$R -$ Reason: Ostrich is a flightless bird.
