(b) single stranded RNA

(c) polyribonucleotides

(d) proteinaceous

Answer 1

 Correct option (b) single stranded RNA

Explanation:

Tobacco Mosaic Virus (TMV) is elongated, rod-shaped, most thoroughly studied plant virus, with 9596 protein and 5% RNA i:e Weight RNA is genomic, i.e. a genetic material which is single-stranded, linear, helically coiled 5 mμ in length with 6500 nucleotides long.
