Answer:

(Choice B) 5 homologous pairs of chromosomes comprising a total of 20 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 5 pairs, 10 chromosomes are present so 10 chromosomes splits into 20 chromatids.
