Answer:
Option A) Double-stranded DNA
Explanation:
Note that the presence of thymine, a pyrimidine nitrogenous base in the genome indicates the presence of DNA.
Then, the summation of 28% adenine + 20% thymine + 35% cytosine + 17% guanine to yield 100% confirms that the DNA is double-stranded.
Thus, the structure of the viral genome is Double-stranded DNA.
I can say for certain that it's really probably not A. or D.
As for B. or C., I'd say C.
The fibrous proteins which are found in connective tissues of the animals are either collagen, elastic, or reticular fibers.
