Answer:
a. things that worked for Hudson, but might not work for them
Step-by-step explanation:
We often follow the advice and success steps of the artist we like and admire. This is because we see that artist as successful and admirable, who has achieved his goals, so we tend to follow a "formula for success" so that we can be as successful as our artists.
However, we must remember that we are different people, and for this reason, what worked with one person will not necessarily work with another. So we can conclude that the correct answer to your question is "things that worked for Hudson, but may not work for them."
