Final answer:
The baseline activity was replaced with a completely different approach for better results.
Step-by-step explanation:
The answer to the question is c) I replaced it with a completely different approach for better results.
When I replaced the baseline activity, I chose a completely different approach to achieve better results because the previous activity was not yielding the desired outcome. By replacing it with a different approach, I hoped to improve efficiency, effectiveness, or any other aspect that was lacking in the initial baseline activity.
This decision was based on careful consideration and analysis of the previous activity and its limitations, as well as the potential benefits and drawbacks of the replacement.
