OA is D. I selected A.

A, C and E: In 1860, the Philological Society LAUNCHED its effort to create a dictionary...although the project TOOK MORE THAN 60 YEARS TO COMPLETE.
Here, launched and took more than 60 years to complete are both in the simple past tense.
Same tense = same time frame.
The implication is that the dictionary was both launched and completed in 1860 -- not the intended meaning.
Eliminate A, C and E.

B: the Oxford English Dictionary had been born
A past perfect verb such as had been born implies an action completed BEFORE another past action.
Here, the implication is that the dictionary had been born BEFORE IT WAS LAUNCHED in 1860 -- a nonsensical meaning.
Eliminate B.

The correct answer is D.

D: although the project would take more than 60 years to complete
One purpose of would is to indicate the future-in-the-past -- an action that takes place AFTER another past action.
Here, the implication is that -- after the dictionary WAS LAUNCHED in 1860 -- it subsequently WOULD TAKE more than 60 years to complete.
