**Core Concept**
Neuropraxia is a type of peripheral nerve injury characterized by transient disruption of nerve conduction due to compression or stretch, without damage to the axon. It involves a temporary loss of nerve function, often reversible, and is classified as a mild nerve injury.

**Why the Correct Answer is Right**
Neuropraxia results in a temporary block of nerve conduction due to a physical insult, such as compression or trauma, which affects the myelin sheath but spares the axon. This leads to a **reduction in conduction velocity** rather than prolongation (so A is incorrect), but the injury is typically **self-limiting** with full recovery expected. Hence, the prognosis is excellent — **good prognosis** (B is correct). Therefore, both statements are true in this context.

**Why Each Wrong Option is Incorrect**
Option A: Prolongation of conduction velocity is incorrect because neuropraxia causes a **conduction block**, not prolonged conduction. Conduction velocity is actually reduced or lost, not prolonged.
Option D: "None" is incorrect because the prognosis is indeed good, making B true — thus, "both" is valid.

**Clinical Pearl / High-Yield Fact**
Neuropraxia is the mildest form of peripheral nerve injury and often resolves spontaneously within weeks. It is commonly seen in cases of nerve entrapment (e.g., carpal tunnel) or mild trauma. Always remember: **"No axonal damage = good prognosis"** — this is key in differentiating neuropraxia from axonal injury.
