Answer:
D. Iterative testing
Step-by-step explanation:
Iterative testing is when you make small changes/ updates to a product based on insights from PREVIOUS test results and user feedback.
So example- Your figuring out if plants grow faster with scheduled watering/feeding times or random watering/feedings. You did the first test run, which was test A. Now your on test B a week later to make sure your results were accurate. You try a different schedule for the feedings (so different times of the day then in test A) but you also have to consider the times you used in test A so you don't just repeat the same thing over again.
I hope that wasn't too wordy, sorry if it was.
