The answer is; Each element will have its own specific spectra.
Every element has its own spectra. Spectra is different for every element because the atoms of elements are different. Spectra is due to the release of a wavelength when an electron of an atom loses energy level. Due to the differences in atomic number and electrons in different elements, the interaction between the nucleus and electrons will cause the electrons in different elements to vary in their energy states and how their transition to other energy levels.

The correct answer is - b. The owl and the robin have more characteristics in common.
All three animals are in fact connected, but the connections are very different. While the owl and the robin are closely related, their connection with the bat can be traced few hundred million years ago. The owl and the robin are both birds, they share common ancestors in the early transitional species of bird-like dinosaurs, and before that their ancestors were part of the dinosaurs. The bat on the other hand, is a mammal, and has evolved from the primitive shrew like mammals that got an open space after the dinosaurs disappeared, and while living along side them were living in their shadow. So the bat's connection to the owl and the robin is going much further into the geologic past, before the diversification of the species to mammals and reptiles.
