The correct option is C Protoplasm
Protoplasm is the colourless material that is composed of the living part of a cell which includes the cytoplasm, nucleus and other organelles. The virus is a small infectious agent which is made of protein coat called capsid that surrounds the genetic material. Some of the viruses also contain an envelope that surrounds the capsid. Protoplasm is absent in virus. So the correct answer is 'protoplasm'.
