**Core Concept**
The cell in question is a type of sensory neuron involved in detecting specific stimuli. It contains specialized ion channels that allow it to respond to changes in its environment.

**Why the Correct Answer is Right**
The correct answer is a **mechano-receptor**. This type of receptor is activated by mechanical stimuli, such as pressure or stretching. The mechanoreceptor contains mechanically gated ion channels, specifically **stretch-activated ion channels**, which open in response to tension. This allows an influx of positively charged ions, leading to depolarization of the neuron and the generation of an action potential.

**Why Each Wrong Option is Incorrect**
* **Option A:** This is not a correct type of sensory neuron. While some sensory neurons may respond to chemical stimuli, the cell in question is specifically activated by mechanical stimuli.
* **Option B:** This is a type of sensory neuron that responds to temperature changes, not mechanical stimuli.
* **Option C:** This is a type of sensory neuron that responds to chemical stimuli, such as odor molecules, not mechanical stimuli.

**Clinical Pearl / High-Yield Fact**
Mechanoreceptors play a crucial role in detecting changes in pressure and tension, which is essential for maintaining proprioception and balance. Damage to mechanoreceptors can lead to impaired proprioception and increased risk of falls.

**Correct Answer:** A. Mechanoreceptor
