GMAT Sentence Correction (SC) | The word 'Buddha' denotes not just the historical figure, Siddhartha

D cannot be the OA. D has several flaws:

(1) the construction not X buy Y is broken as you can see: The word 'Buddha' denotes notjust the historical figure , Siddhartha Gautama, but, like 'president' or 'priest',refers to a type of person , - in this case, one who has achieved enlightenment.

'just' and 'refers' cannot be parallel.

(2) D compares 'the word' to 'president'/'priest' which is nonsense.

=> D cannot be the OA.

I think E will be a better choice in this case.
