Consider the given two statements regarding frog:
Statement I: The nervous system is organised into a central nervous system (brain and spinal cord), a peripheral nervous system (cranial and spinal nerves) and an autonomic nervous system (sympathetic and parasympathetic) and there are ten pairs of cranial nerves arising from the brain.
Statement II: The brain is divided into fore-brain, mid-brain and hind-brain where the forebrain includes olfactory lobes, paired cerebral hemispheres and unpaired diencephalon, the midbrain is characterised by a pair of optic lobes and the hind-brain consists of cerebellum and medulla oblongata.
