C. Statement-1 is true, statement-2 is false
D. Statement-1 is false, statement-2 is true

Answer

To analyze the given statements about amorphous solids, let's break down the reasoning step by step:

### Step 1: Understand the concept of isotropy
- **Isotropy** refers to the property of a material where its physical properties are the same in all directions. This means that if you measure a property (like strength or conductivity) in any direction, you will get the same value.

**Hint:** Recall that isotropic materials have uniform properties regardless of the direction of measurement.

### Step 2: Analyze Statement 1
- **Statement 1:** "Amorphous solids are isotropic."
- Amorphous solids, such as glass or certain plastics, lack a long-range order in their atomic arrangement. This irregular structure leads to uniformity in their physical properties in all directions.

**Hint:** Think about how the lack of a structured arrangement in amorphous solids contributes to their isotropic nature.

### Step 3: Analyze Statement 2
- **Statement 2:** "Amorphous solids show physical properties like mechanical strength, electrical conductivity, refractive index, etc., the same in all directions."
- Due to the short-range order and random arrangement of particles in amorphous solids, their physical properties do not vary with direction. This means that mechanical strength, electrical conductivity, and refractive index are consistent regardless of the direction in which they are measured.

**Hint:** Consider how the random arrangement of atoms in amorphous solids affects their physical properties.

### Step 4: Conclusion
- Since both statements are true and the second statement provides a correct explanation for the first, we conclude that:
- **Both Statement 1 and Statement 2 are true.**
- **Statement 2 correctly explains why Statement 1 is true.**

**Final Answer:** Both statements are true, and Statement 2 is the correct explanation for Statement 1.
