Options

A. audition
B. gustation
C. equilibrium
D. olfaction

Explanation

To determine the ability to perceive pheromones, we need to identify which sense is related to this perception. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understanding Pheromones**: Pheromones are chemical signals produced by living organisms, including animals and insects. They are used for communication, especially in mating and territorial behaviors.

2. **Identifying the Senses**: The question provides four options:
- Odation
- Custacean
- Equilibrium
- Olfaction

3. **Analyzing Each Option**:
- **Odation**: This term is not commonly used in the context of sensory perception.
- **Custacean**: This refers to a class of animals (like crabs and lobsters) and is not related to senses.
- **Equilibrium**: This refers to balance and spatial orientation, not related to chemical perception.
- **Olfaction**: This is the sense of smell, which is directly involved in detecting pheromones.

4. **Conclusion**: Since pheromones are detected through smell, the ability to perceive pheromones is related to the sense of **Olfaction**.

### Final Answer:
The ability to perceive pheromones is related to the sense of **Olfaction**.
