The component that is present in some viruses but absent in others is known as viral envelope or simply as C) envelope.
Explanation:
The envelope in virus is nothing but the protective layer covering its protective protein capsids. They are usually derived from the host's cell membranes but do include viral glycoproteins as well. It usually helps the viruses avoid the host immune system. They serve the virus in helping them enter the host system and infect the host.
