**Core Concept**
Acute inflammatory demyelinating polyradiculoneuropathy (AIDP), porphyric neuropathy, and lead intoxication primarily affect the motor nerves, leading to predominant motor neuropathy. This is characterized by weakness, muscle wasting, and fasciculations, particularly in the proximal muscles.

**Why the Correct Answer is Right**
Arsenic intoxication, on the other hand, is a predominantly sensory neuropathy. Arsenic exposure leads to damage of the sensory nerves, resulting in symptoms such as numbness, tingling, and pain in the hands and feet. This is because arsenic primarily affects the small nerve fibers responsible for transmitting sensory information.

**Why Each Wrong Option is Incorrect**
**Option A:** AIDP, also known as Guillain-Barré syndrome, is a classic example of a motor neuropathy, with muscle weakness and paralysis being the primary symptoms.
**Option B:** Porphyric neuropathy is a type of motor neuropathy that occurs in patients with acute intermittent porphyria, characterized by abdominal pain, muscular weakness, and neuropathic symptoms.
**Option C:** Lead intoxication also causes a predominantly motor neuropathy, with symptoms including weakness, fatigue, and neuropathic pain.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that arsenic intoxication can also cause gastrointestinal symptoms, such as nausea, vomiting, and diarrhea, in addition to its predominantly sensory neuropathy.

**Correct Answer Line**
✓ Correct Answer: D. Arsenic intoxication
