I would say either a or b because when dealing with stress you want to reflect on things you’ve done in the past and see how they resulted, but then it also helps to have the ability to laugh at yourself because it can make the situation less stressful. Hope that helped a little
I think the correct answer is B. Learning new word. Because Managing felling is about emotion which is not language skills and memorizing a pattern is about the brain so Learning new words is the right choice
