D. Drug

Answer

To determine which category rubber, gums, and cellulose belong to, we can analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding the Options:**
- **Polymeric Substances:** These are large molecules made up of repeating structural units (monomers). They are often produced by living organisms and can include natural substances like rubber, gums, and cellulose.
- **Pigments:** These are substances that impart color to plants and other organisms. Examples include chlorophyll and carotenoids.
- **Essential Oils:** These are concentrated volatile oils extracted from plants, known for their aromatic properties. Examples include lavender oil and peppermint oil.
- **Drugs:** These are chemical substances that can alter physiological functions and are often derived from plants or synthesized. Examples include curcumin from turmeric.

2. **Analyzing Rubber, Gums, and Cellulose:**
- **Rubber:** This is a natural polymer that can stretch and return to its original shape. It is classified as an elastomer.
- **Gums:** These are polysaccharides that are secreted by plants, often used for their thickening properties.
- **Cellulose:** This is a carbohydrate polymer that forms the structural component of plant cell walls.

3. **Conclusion:**
- Since rubber, gums, and cellulose are all made up of repeating units and are produced by plants, they fit the definition of polymeric substances.

4. **Final Answer:**
- Therefore, the correct answer is **Polymeric substances**.
