Statement I: The PNS comprises of all the nerves of the body associated with the CNS.
Statement II: The CNS is divided into two divisions called somatic neural system and autonomic neural system.
Statement I is correct but Statement II is incorrect.

Why (B) is correct:
Statement I is correct. The Peripheral Nervous System (PNS) indeed consists of all the nerves (cranial and spinal nerves) that originate from or terminate in the Central Nervous System (CNS), connecting the CNS to the rest of the body.
Statement II is incorrect. The CNS (brain and spinal cord) is a distinct division. It is the PNS that is further divided into the somatic neural system and the autonomic neural system, not the CNS.
Why other options are wrong:
A) Both statements are not correct, as Statement II is incorrect.
C) Statement I is correct, so this option is wrong.
D) Statement I is correct, so both statements are not incorrect.
Common Mistake: Students often confuse which system (CNS or PNS) is further subdivided into somatic and autonomic neural systems.
NEET Tip / Mnemonic: Remember that the PNS is Peripheral, meaning it's the part that branches out to the Parts of the body, and it's further divided into Somatic (voluntary) and Autonomic (involuntary) systems. Think of CNS as the 'main office' and PNS as the 'field agents'.
Correct Answer: (B)
Statement I is correct but Statement II is incorrect.
