C. `{:(X, Y, Z),("Bird ", "Bat","Homologous"):}`
D. `{:(X, Y, Z),("Bird ", "Insect","Analogous"):}`

Answer

A

Explanation

Analogous organs (structures) are those organs which have similar functions but are different in their structural details and origin. Wings of bat and bird are analogous organs. Wings of bat are skin folds stretched mainly between elongated fingers, but the wings of a bird are feathery covering all along the arm. The basic designs of the wings of bat and the bird, their structure and components are very different. They only look similar because both are adapted for flying but their origin is different.
