The choices can be found elsewhere and as follows:
a. partly an issue of production.
b. partly a political issue.
c. a problem that threatens world peace.
d. All of these are correct.
I believe the correct answer is option D, all of the above. Taken together, the sociological approaches to global poverty show us that poverty is partly an issue of production, partly a political issue and a problem that threatens world peace. Hope this answers the question.
