### Step 1: Identify Components of Linux Architecture
To answer the question, we need to understand the functions of each component in the Linux architecture:
1. **Kernel**: The core component of the Linux operating system that interacts directly with the hardware.
2. **Graphics Server**: Manages graphical output and input, but sits on top of the kernel.
3. **Applications**: User-facing programs that run on the operating system.
4. **OS Shell**: Provides a user interface to interact with the operating system but does not communicate with hardware directly.

### Step 2: Analyze the Functionality
- The **Kernel** is responsible for managing system resources, facilitating communication between hardware and software, and providing essential services for all other parts of the system. Thus, it functions closest to the hardware.
- The **Graphics Server**, **Applications**, and **OS Shell** are built on top of the kernel and do not interact with the hardware directly.

### Step 3: Conclusion
Based on the analysis, the component of Linux architecture that functions closest to the hardware is the **Kernel**.

### Final Answer
**A. Kernel**
