I felt that if 'that' is not followed after theory , the meaning is distorted hence eliminated D and E . And out of the three it was very clear A conveys the meaning properly with parallelism and correct grammar construction .
On thinking again as how to differentiate between A nd E . Here as per construction support .. that .. should be followed by the explanantion of the theory .
Support ' what ' That 'concept of the theory '
And in E , if u read it properly it changes the meaning saying that it was the 'theory ' that was in the centre of the universe . But in A it clearly says that it is the 'black hole' that is in the centre of the universe ...
hope its clear
