**The Correct Relationship Within Each Pair of the Natural Product is:**
The correct relationship within each pair of the natural product is option 'A': Camphor-terpene; insulin-protein; nicotine-alkaloid; streptomycin-carbohydrate.
**Explanation:**
To understand the correct relationships within each pair of the natural products, we need to define and understand the nature of each term.
1. **Camphor** is a natural product that belongs to the terpene class. Terpenes are a large and diverse class of organic compounds found in plants. They are often responsible for the characteristic scents and flavors of plants and are involved in various biological functions.
2. **Insulin** is a protein. Proteins are large, complex molecules that are essential for the structure and function of cells in living organisms. Insulin is a hormone produced by the pancreas that regulates blood sugar levels.
3. **Nicotine** is an alkaloid. Alkaloids are a class of nitrogen-containing organic compounds that are commonly found in plants. Nicotine is a highly addictive compound found in tobacco plants.
4. **Streptomycin** is an antibiotic that belongs to the class of aminoglycosides. Aminoglycosides are a group of antibiotics that are derived from sugars. Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen, and they include sugars and starches.
Therefore, the correct relationships within each pair of the natural product are:
- Camphor is a terpene.
- Insulin is a protein.
- Nicotine is an alkaloid.
- Streptomycin is a carbohydrate.
Thus, option 'A' is the correct relationship within each pair of the natural products.
