Answer:
Option B. Viral genes may be encoded by DNA or RNA, but cellular genes are always encoded by DNA.
Explanation:
Virus is a unique organism having unique characteristics which act as both living and non living. In cell, it is living while outside the cell it is present in crystalline form. Virus is composed of two genome i. e. DNA or RNA. But cell is composed of only DNA genome. There is no nucleus present in virus. Mitochondria and ribosome are also absent.

Options:
A. Analogous structures
B. Vestigial structures
C. Homologous structures
D. Missing links
Analogous structures is the illustration in cephalopod. Thus, the correct option is C.
A cephalopod eye, unlike a vertebrate eye, is focused through movement, similar to a camera or telescope lens, rather than altering shape like a human eye lens. The lens, which is totally internal, is nearly spherical, as is the eye.
<h3>
What are the characteristics of cephalopod?</h3>
- Organs. They have three hearts, two of which transport blood to the gills and the other which pumps blood throughout the body. Their blood is blue because the protein hemocyanin binds oxygen.
- Color. Cephalopods have the ability to change the color of their skin at will. They can even use their skin to create elaborate patterns and forms. This is accomplished by the use of chromatophores, which are pigment-filled bags found in the skin. Nerves can change the color of the skin by controlling these chromatophores.
- Diet. Cephalopods are all carnivorous animals.
Organs, tissues, or cells in the body that are no longer functional in their ancestral version of the trait are known as vestigial organs.
