Solution
The correct option is A Arolium
All cockroaches, possess smooth flexible pads found at the distal end of the leg on the tarsus. There are five pads altogether; the first four segments of the tarsus contain pads called as the euplantula, while the most flexible fifth segment found at the distal end of the tarsus and is called as the pretarsus, which is made up of a broadly triangular adhesive pad called the arolium and two pretarsal claws.
The pretarsal claws allow cockroaches to grip and move over rough surfaces.
The arolium is the adhesive organ of the cockroach foot engaged when the legs are pulling and used in scaling and adhering to smooth surfaces. So, the correct answer is option A.
