**Experiment on the Effect of Pesticides on Fruit Flies**

A scientist conducted an experiment to study the effect of a pesticide on fruit flies. The setup involved two jars: Jar A containing no pesticide and Jar B containing a pesticide. Each jar initially contained 10 fruit flies. The results of the experiment are depicted in the graph below.

**Graph Explanation:**

- **Title:** Toxic Effect of Pesticide on Fruit Flies
- **Y-axis:** Number of Fruit Flies (Survival Rate), ranging from 0 to 11.
- **X-axis:** Jars A and B.
- **Bars:**
  - **Jar A (No Pesticide):** Shows 9 surviving fruit flies.
  - **Jar B (Pesticide):** Shows 1 surviving fruit fly.
- **Legend:**
  - A bar colored to indicate "No Pesticide"
  - A bar colored to indicate "Pesticide"

**Question:**

Which of the following variables is independent in this experiment?

- The number of jars used in the experiment
- Number of fruit flies used in the experiment
- Survival rate of fruit flies
- Presence of the pesticide

*Note: The independent variable in this context is the presence of the pesticide, as it's the factor that is being manipulated to observe its effect on the fruit flies.*
