D. 4

Answer

To solve the question regarding the total number of fundamental spatial arrangements possible in crystal lattices, we will follow these steps:

### Step 1: Understand the Concept of Lattice Points
Lattice points represent the positions of particles (atoms, ions, or molecules) in a crystal structure. These points are arranged in a specific geometric pattern to form a crystal lattice.

**Hint:** Remember that lattice points can represent different types of particles in a solid.

### Step 2: Define Space Lattice
A space lattice is a three-dimensional arrangement of lattice points that shows how the particles are positioned in space. It is a regular arrangement that helps in visualizing the structure of the solid.

**Hint:** Think of space lattice as a 3D grid where each point corresponds to a particle.

### Step 3: Identify the Types of Crystal Systems
There are seven distinct types of crystal systems based on the arrangement of lattice points. These are:
1. Triclinic
2. Monoclinic
3. Orthorhombic
4. Tetragonal
5. Hexagonal
6. Rhombohedral
7. Cubic

**Hint:** Try to visualize each type of crystal system and how they differ in terms of symmetry and dimensions.

### Step 4: Count the Total Arrangements
By identifying the seven types of crystal systems, we can conclude that the total number of fundamental spatial arrangements possible in crystal lattices is seven.

**Hint:** Make sure to remember that each type of arrangement corresponds to a unique geometric configuration.

### Final Answer
The total number of fundamental spatial arrangements possible in crystal lattices is **seven**.
