| I: | Myelinated nerve fibres are enveloped with Schwann cells, which form a myelin sheath around the axon. |
| II: | Unmyelinated nerve fibre is not enclosed by a Schwann cell or a myelin sheath. |
| III: | Myelinated nerve fibres are found in spinal and cranial nerves. |
| IV: | Unmyelinated nerve fibres are commonly found in autonomous and somatic neural systems. |
| 1. | Only II is incorrect | 2. | I and II are correct |

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
| Assertion (A): | Action potential propagation in unmyelinated neurons is faster than in myelinated neurons. |
| Reason (R): | Myelin is a complex polysaccharide and it slows the conduction of the impulse along the axonal membrane. |
In the light of the above statements choose the correct answer from the options given below:
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |
