Premise 1- Oil Companies - Poor Corporate Citizen because they oppose Govt Action on Global warming which is based on scientific studies that term Global Warming as severe.

Premise 2 - Same companies spend dollars in scientific study to study effects of climatic change.

To solve this discrepancy that Oil Companies are on one hand opposing govt action (to oppose global warming, based on scientific studies) and on the other hand same companies are spending dollars to address Climatic change.

We need some info which can justify this disconnect between money spent by oil companies and where it is spent.

(A) Time duration not sufficient.
(B) Very finely proves that if the Oil companies are putting dollars to find out effects of climatic change then they very well believe that global warming can bring climatic change, thus they cannot refute Govt's action to oppose global warming by undermining the scientific study
(C) Profits. Not related here.
(D) Incorrect because if that scientific study is not proven yet then there is no discrepancy.
(E) What oil companies believe or not does not help solve the discrepancy.

I had to chose b/w B and D, and I think D is better, any thoughts, anyone?
How do I eliminate D?

the official Explaination is as follows:
The passage describes an apparent discrepancy. On the one hand oil companies
undermine scientific research that portrays global warming as a severe problem,
presumably because this research will lead to government action that might harm
the companies' profits. On the other hand, these same companies invest millions
of dollars in climate change research. The correct answer must provide a motive
for the companies to invest in certain research related to global warming.
(A) This choice establishes a time frame for when the oil companies began
investing research dollars. However, it does not provide a reason as to why they
would make this investment.
(B) CORRECT. This choice provides a motive for companies to invest in global
warming research. If the research is specifically geared at developing
technologies used to combat global warming, this research represents a longterm
strategy for finding new ways for the companies to profit. This is in contrast
with the research that the oil companies oppose - research focused on the
severity and immediacy of the issue, a focus which might lead to government
action that could have a negative impact on the profitability of the oil companies
in the short term.
(C) The fact that the government action would negatively affect the oil companies
explains why they would oppose this scientific research. It does not provide a
reason why they would also invest in scientific research related to global
warming.
(D) The fact that the scientific data related to the severity of global warming is not
definitive does not provide a reason as to why oil companies would invest
millions of dollars in research that accepts that global warming will have longterm
affects.
(E) If oil companies didn't believe that any scientific research related to climate
change will serve their interests, there would be no reason for them to invest any
money in such research.
