What is the primary method of classification of viruses?
A
by nucleic acid
B
by capsule shape
C
by envelope composition
D
virulence
E
method of infection
Explanation: 

Detailed explanation-1: -Baltimore classification (first defined in 1971) is a classification system that places viruses into one of seven groups depending on a combination of their nucleic acid (DNA or RNA), strandedness (single-stranded or double-stranded), sense, and method of replication.

Detailed explanation-2: -Virus classification is based mainly on characteristics of the viral particles, including the capsid shape, the type of nucleic acid (DNA or RNA, double stranded (ds) or single stranded (ss)) within the capsid, the proces s of replication, their host organisms, or the type of disease they cause.

Detailed explanation-3: -Viruses are classified on the basis of morphology, chemical composition, and mode of replication.

Detailed explanation-4: -Baltimore classification is a system used to classify viruses based on their manner of messenger RNA (mRNA) synthesis. By organizing viruses based on their manner of mRNA production, it is possible to study viruses that behave similarly as a distinct group.
