Hi stop,


See , This sentence has more to do with the style.
First of all, we need to understand that new evidence has provided the support for the theory ..... and yes theory is not of global forest fires....... but theory says that global fores fires contributed to the extinction.......

Once we identify the correct meaning, we can eliminate A C and E .. for distorting the meaning...

Now if you read D, the construction........

in support of the theory that........X.......and that...........Y.
wrognly compares X and Y suggesting that both X AND Y are two separate theories........

In fact, both X and Y ARE parts of one theory........

This fact is correctly stated in B
