The correct options are
A 10th and segment
B 11th segment
The 9th to 11th segments in a leech is called the clitellar region. This region consists of a temporary clitellum. The male and female genital pores are presnet on the 10th and 11th segments of the clitellar region. The clitellum is a thick, saddle-like ring found in the epidermis (skin) of the leech. It forms a cocoon for it's eggs and secretes a viscous fluid and is used in the process of sexual reproduction in annelids like leeches.
