Question Analysis
This question tests the application of the concept of zero slope in a real-world context. The height of the tree remains constant over time, indicating a horizontal line on a height-time graph.

Key Concept Explanation
The key concept here is that the slope of a horizontal line is always zero, as there is no change in the y-value (height) as the x-value (time) changes.

Step-by-step Solution
1. Recognize that the height of the tree does not change over time.
2. Understand that this situation can be represented by a horizontal line on a height-time graph.
3. Recall that the slope of a horizontal line is given by the formula .
4. Since
