Explanation

**Step-by-Step Solution:**

1. **Understanding Ecology**: Start by recognizing that ecology is the study of interactions between organisms and their environment. It can be divided into two main branches: Synecology and Autecology.

2. **Defining Autecology**: Autecology specifically focuses on the relationship of an individual organism or a single species with its environment. This includes how an individual interacts with biotic (living) and abiotic (non-living) factors in its surroundings.

3. **Identifying the Options**: The question provides four options:
- a) Relation of a population to its environment
- b) Relation of an individual to its environment
- c) Relation of a community to its environment
- d) Relation of a biome to its environment

4. **Analyzing the Options**:
- Option (a) refers to population ecology, which studies groups of individuals.
- Option (b) refers to Autecology, which is the focus of the question.
- Option (c) refers to Synecology, which studies communities.
- Option (d) refers to biomes, which is a broader ecological level.

5. **Selecting the Correct Answer**: Since the question specifically asks about Autecology, the correct answer is option (b) - "relation of an individual to its environment."

**Final Answer**: Autecology is the relation of an individual to its environment.
