Question Analysis
This question involves distinguishing between correlation and causation in an experimental context.
The main focus is on recognizing that controlled experiments with random assignment can establish causation.

Key Concept Explanation
Causation is confirmed when a controlled experiment shows that changing one variable (the cause) directly results in changes to another variable (the effect), with other factors held constant.
Correlation lacks such experimental control and only shows association.

Step-by-Step Solution
Analyze the setup: The experiment uses random assignment and controls for other factors (only sunlight differs between groups).
Evaluate the relationship: The difference in growth is directly attributed t...
