Correct option is B

One pair of ovaries attached to the intersegmental septum of 12th and 13th segments. Testes are present in 10th and 11th segments (not 11th and 12th). Spermathecae are four pairs in number (6th to 9th segments). Prostate glands are one pair in number and extend from 16th or 17th segment to 20th or 21st segment.
