**Core Concept**
A Faraday cage is a mesh of conductive material (like copper wire mesh) that distributes electromagnetic charges evenly, effectively shielding the interior from external electromagnetic disturbances. This principle is crucial in radiology and EEG (electroencephalogram) cabins to minimize electrical interference and ensure accurate measurements.

**Why the Correct Answer is Right**
The correct answer is the Faraday cage because it is a specific type of shielding that utilizes the even distribution of electromagnetic charges to cancel out external electromagnetic fields. In an EEG cabin, the Faraday cage is essential to prevent external electromagnetic disturbances from interfering with the delicate signals being measured from the brain. The continuous sheet of copper wire mesh effectively distributes the electromagnetic charges, shielding the interior from external electromagnetic noise.

**Why Each Wrong Option is Incorrect**
**Option A:** Maxwell cage - This is incorrect because James Clerk Maxwell was a Scottish physicist who formulated the equations of electromagnetism, but he is not associated with the concept of a shielding cage.
**Option B:** Edison's cage - This is incorrect because Thomas Edison was an American inventor who developed the first practical incandescent light bulb, but he is not associated with the concept of a shielding cage.
**Option D:** Ohm's cage - This is incorrect because Georg Ohm was a German physicist who formulated Ohm's law, but he is not associated with the concept of a shielding cage.

**Clinical Pearl / High-Yield Fact**
When designing a shielding system, the key principle is to ensure that the conductive material is continuous and evenly distributed to effectively cancel out external electromagnetic fields. This is a critical consideration in radiology and EEG cabins to prevent electrical interference and ensure accurate measurements.

**✓ Correct Answer: C. Faraday cage**
