Answer 2

The right answer of the question is the last one.

It is located at the last: the 7th abdominal segment contains the largest abdominal ganglia in a cockroach’s body.

Each ganglion of the nerve cord is molded by the union of 2 ganglia excluding the ganglion within the 7th segment. In a cockroach the nervous system is spread all through the body.
