Diane has a plan to improve her responsibility. in order to understand if she has met her goal, she must a. formulate a new goal b. record her progress c. accomplish harder tasks d. ask others for their opinions

B, record her progress.

This answer makes the most sense.

One wouldn't formulate a new goal to see if they were able to met the goal.

Accomplishing harder tasks is a good thing to do, but it still doesn't show if she has improved her responsibility goal.

Finally, ask others for their opinions seems somewhat farfetched. Yes, in certain circumstances this would be important to do but for what she wants to do, it's not important.

Hopefully this helped.

here you go hope it heps "horace mann"
