The sentence talks about the increasing number of refugees from countries that experience abundance of conflict, environmental disasters, economic hardships and unstable leadership. The phrase 'rife with' something means full of something unpleasant. The other options except (c) are incorrect because the use of prepositions like 'within', 'by', 'after' and 'before' render the phrase meaningless. Hence, (c) is the correct answer.
