Answer:

(Choice B) 555 homologous pairs of chromosomes comprising a total of 202020 chromatids

Explanation:

Homologous chromosome are those two chromosomes which have same gene but different in shape and appearance. Chromatids are the identical copies of chromosome. Single chromosome splits into double number of chromatids. In 555 pairs, 101010 chromosomes are present so 101010 chromosomes splits into 202020 chromatids.
