Scientists studying the region are divided over how much of the temperature shift is due to the region's large natural variations and how much is being driven by the global buildup of carbon dioxide and other heat-trapping greenhouse gases, like those emitted by tailpipes.

A: is being driven by the global buildup of carbon dioxide and other heat-trapping greenhouse gases, like
B: the global buildup of carbon dioxide and other heat-trapping greenhouse gases drive, such as
C: the global buildup of carbon dioxide and other heat-trapping greenhouse gases drive, like
D: is driven by the global buildup of carbon dioxide and other heat-trapping greenhouse gases, such as
E: is being driven by the global buildup of carbon dioxide and other heat-trapping greenhouse gases, such like

OA: D
I have eliminated A, C and E. what about B and D?
I selected D but it is wrong. Solution talks about parallelism.

If I select D

Scientists studying the region are divided over how much of the temperature shift is due to the region's large natural variations and how much of the temperature shift is driven by the global buildup of carbon dioxide and other heat-trapping greenhouse gases, such as those emitted by tailpipes.
