Correct answer
D. (A) - (II), (B) - (I), (C) - (IV), (D) - (III)
Step-by-step solution
In cockroaches, the 10^ th segment bears a pair of jointed filamentous structures called anal cerci in both sexes. Anal styles are short, thread-like structures present only in males on the 9^ th sternite. The female genital pouch is formed by the 7^ th , 8^ th , and 9^ th sternites. The male genital pouch lies at the hind end of the abdomen and is bounded dorsally by the 9^ th and 10^ th terga and ventrally by the 9^ th sternite. Therefore, the correct matching is (A) - (II), (B) - (I), (C) - (IV), (D) - (III). An
