Which One of the Following BEST Describes Why Genome Sequencing

Which one of the following BEST describes why genome sequencing can be complicated by repeated sequences?

A) The repeated sequences are often longer than the sequences obtained by automated sequencing.
B) Automated sequencing devices interpret repeated sequences as a single-copy sequence.
C) Repeated sequences artificially inflate the genome size, leading to an exaggerated interpretation of the complexity of the organism.
D) The repeated sequences are too small to gather usable sequence information from.
E) All of these choices are correct.
