A.

Act again

Explanation:

Makes sense when you think about it.

In the question, it's asking you what would be the next step after adjust when you track your progress.

When you're tracking progress, the most important thing to do is keep consistent with what you're doing until you hit the goal.

This answer would be the most reasonable in this context, due to the fact that you would need to repeat the act, possibly improve the act, when you're tracking your progress to see if anything changed.

If you stop "acting" on the progress you're trying to track, then the data that you would receive from tracking the progress would not be consistently increasing in a business stand point. In a business, if you observe and notice that something is not right, you would adjust whatever is wrong and would "repeat" the act, or act again, in order to see if progress has been made form the previous act.
