Question

• A. 6
• B. 10
• C. 11
• D. 12

Answer 1

The correct option is B 10

The abdomen in a cockroach in both males and females consists of 10 segments. In females, the 7th sternum is oat shaped and together with the 8th and 9th sterna forms a brood or genital pouch whose anterior part contains female gonopore, spermathecal pores, and collateral glands. In males, genital pouch or chamber is present at the hind end of the abdomen bounded dorsally by 9th and 10th terga and ventrally by the 9th sternum.

So the correct answer is '10'.
