Which structures are found in all viruses? a capsid and genetic material a protein coat and dna a promoter and genetic material a plasma membrane and protein coat

The correct answer is option A, a capsid and genetic material

Reason -

The three major parts of a virus are as follows –  

a)Protein Capsid – Virus genetic material(genome) is covered by a protein shell which is known as capsid.  

b)Lipid Envelope – Further the Protein Capsid (also referred as nucleocapsid) is surrounded by a membrane called as envelope.  

c)Viral genome – It mainly consists of single or double stranded DNA or RNA (carry the genetic material) which can be double or single stranded or may have some other form of structure.
