• Each ovary is whitish made of finger-like lobules in which ova are arranged in various stages of development.
• An oviductal funnel lies immediately behind each ovary in the 13th segment and it leads into a short oviduct.
• Both the oviducts converge and form a single female genital aperture at the 14th segment.
  

So, the correct answer is option A.
