Detailed Solution

Concept: Here, the subject 'discussion' is singular and calls for the singular verb 'has' and now no longer the plural 'have'. Thus, alternatives A and D are incorrect. The use of 'focus' has to be accompanied by a way of means of the preposition 'on' - which isn't always so withinside the case of B. Therefore, B isn't always our answer. The use of 'and' needs a parallel structure -- here, this parallel creation has to be 'whether or not the earth could develop warmer' and if so, 'to what extent'. By this logic, the most effective alternative C befits the context.
Hence, option 3 is correct.
