@brazilianengstudent,
The reason I was guessing B (rightly, or wrongly), is this:
"APPROACH" is a verb, so I eliminated Option D ("achieved"), but A, B, or C would work.
"SOCIOCULTURAL" merges two words, so I eliminated C, leaving A or B.
And the word "INTERACTIONAL" seemed more like "scholarship" than "themselves", to me.
That's the best I can do.
