The best answer is d - while comparing the data with the hypothesis. The scientific method defines the correct steps as:
1. observation - use of the five senses to learn about something.
2. Question - where you raise questions based on your observation.
3. Hypothesis - a prediction or guess of what the answer to the question is.
4. Method - point where you test the hypothesis by carrying out an experiment.
5. Results / data - this is what happened after each step of the experiment.
6. Conclusion - where the results of the experiment are discussed and it is summarized if the prediction was true or not, based on data from the results.
D. It happens all the time
The term precision is how repeatable the experiment is
Accuracy is how close to the right answer you are.
