Options:
Answer:
D
Solution:
The neural organisation is very simple in lower invertebrates. For example, inHydra, it is composed of a network of neurons. The neural system is better organised in insects, where a brain is present along with a number of ganglia and neural tissues. The vertebrates have a more developed neural system.
