Explanation

To solve the question "Which of the materials given below is made by human?", follow these steps:

### Step 1: Understand the Types of Materials
- Materials can be classified into two categories: natural materials and man-made (synthetic) materials.
- Natural materials are derived from natural sources such as plants and animals, while man-made materials are created through chemical processes by humans.

### Step 2: Identify the Given Options
- You need to look at the options provided in the question. Although the options are not listed here, let's assume they include materials like cotton, silk, glass, PVC, and nylon.

### Step 3: Classify Each Material
- **Cotton**: This is a natural fiber obtained from the cotton plant.
- **Silk**: This is also a natural fiber, produced by silkworms.
- **Glass**: This is a man-made material, created by heating sand and other ingredients.
- **PVC (Polyvinyl Chloride)**: This is a synthetic plastic made from vinyl chloride.
- **Nylon**: This is a synthetic polymer developed by humans.

### Step 4: Determine Which Material is Man-Made
- From the classification:
- Natural materials: Cotton, Silk
- Man-made materials: Glass, PVC, Nylon
- The question specifically asks for the material that is made by humans.

### Step 5: Choose the Correct Option
- Based on the classification, the correct answer would be any of the man-made materials listed (Glass, PVC, Nylon). If you were to choose one, you could select "Nylon" as a common example of a synthetic fiber.

### Final Answer
- The correct option is **Nylon** (or any other man-made material listed).
