Solution

The correct option is D It confirms that DNA is the carrier of genetic information
Pedigrees are used to analyze the pattern of inheritance of a particular trait throughout a family. Pedigrees show the presence or absence of a trait as it relates to the relationship among parents, offspring, and siblings.
By analyzing a pedigree, we can determine genotypes, identify phenotypes, and predict how a trait will be passed on in the future. The information from a pedigree makes it possible to determine how certain alleles are inherited: whether they are dominant, recessive, autosomal, or sex-linked.
The pedigree analysis does not confirm that DNA is the carrier of genetic information

So, the correct answer is 'It confirms that DNA is the carrier of genetic information'.
