Answer:
Letter B: Scientist must be able to express their work to other scientists and to the general public.
Explanation:
Scientists talk with everyone about they're work. Everyone needs to know their work,not everytime but they do. Public can also tell them they're ideas.
Assuming this question is in Spanish, and not English, the correct answer is B. first and second person plural.
Take a stem changing verb in Spanish, such as decir (= to say). This is how it's conjugated: yo digo, tu dices, el/ella dice, nosotros decimos, vosotros decis, dicen.
As you can see, nosotros and vosotros (first and second person plural) are the only forms whose stem doesn't change, whereas that change occurs in all other persons.
I would think the first option.
