To solve the question "Condition of suspended growth due to external environmental condition is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- We need to clarify the terms related to plant growth and environmental conditions. The key terms here are dormancy and quiescence.

2. **Define Dormancy**:
- Dormancy refers to a state in which a seed or plant is alive but not actively growing. This condition is often triggered by environmental factors such as temperature, moisture, and light.

3. **Define Quiescence**:
- Quiescence is a state of suspended growth where the plant or seed is not actively growing but can resume growth when conditions become favorable. This state is also influenced by external environmental conditions.

4. **Analyze the Options**:
- The options given are:
1. Dormancy
2. Rest
3. Quiescence
4. All of the above
