Answer 1

The correct option is B $5^{th}$ and $6^{th}$ terga of cockroach

Stink glands produce a secretion that gives a characteristic stinky smell to the cockroach and helps in a defensive mechanism. The arthrodial membrane between the $5^{th}$ and $6^{th}$ abdominal terga is depressed on both sides to make stink glands. They are present in both male and female cockroaches.
