Step-by-step solution
In both male and female cockroaches, the 10th segment bears a pair of jointed filamentous structures called anal cerci (A matches IV). Males bear a pair of short, threadlike anal styles which are absent in females (B matches I). In females, the 7th sternum is boat shaped and together with the 8th and 9th sterna forms a brood or genital pouch (C matches II). In males, the genital pouch or chamber lies at the hind end of the abdomen and is bounded dorsally by the 9th and 10th terga and ventrally by the 9th sternum (D
