C) 3
D)1 and 3
E) All of these

The human genome is highly variable, and this variability is due to a combination of factors, including silent mutations (which do not change the amino acid sequence of proteins), mutations in non-coding regions (which can affect gene regulation and other aspects of genome function), and larger-scale genomic rearrangements like duplications and deletions. All these factors contribute to the genetic uniqueness of individuals.
