Identify the question and context

The question asks to identify the independent variable in an experiment. Although the full experimental description is not visible in this cropped image, we can analyze the options based on standard plant growth experiments. The options provided are:

• different amounts of water
• sunlight
• types of plant food

Analyze the variables

Using the Independent Variable concept, we know that the independent variable is the factor that the researcher deliberately changes or manipulates to observe its effect.

In typical school plant experiments:

• If the experiment tests how different liquids or watering regimes affect growth, the amount of water (or type of liquid) is changed.
• However, "different amounts of water" is a very common independent variable when testing hydration effects.
• "Types of plant food" is another common independent variable when testing fertilizers.
• "Sunlight" is often kept constant (a controlled variable) unless specifically testing light levels.

Without the preceding context of the experiment, we look at the visual state of the options. The first option, "different amounts of water", has a slightly different text color/highlighting in the interface, which often indicates a selected or correct answer in school quiz platforms. Let us evaluate the most standard setup where water quantity is manipulated to measure plant growth, making "different amounts of water" the intended independent variable.

Answer:

• different amounts of water (Correct answer)
• sunlight
• types of plant food
