I couldn't eliminate (A) as there are correct OG answers where the subject of the clause need not be the agent/actor of the modifier (present participial phrase) action
OK, so let's say that the subject is not the agent of "making." What would be the agent of "making"? In other words, what is there in the universe that would be "making" the birth a landmark development?
Does the fact that "A Sumatran rhinoceros was recently born in a Cincinnati zoo" make the birth a landmark development? It' doesn't, right?
And the noun phrase "the first birth in captivity of that species in more than a century" doesn't make the birth a landmark development. After all, the birth would not make itself a landmark development.
So, in short, the problem with (A) is that there is no thing or fact that is making the birth a landmark development. So, the use of "making" doesn't make sense.

I eliminated (D) as "The recent birth of X....is a landmark development" didn't make sense. Probably because I missed out on the fact that landmark is acting as an adjective.
Yes, the meaning conveyed is that the birth is the development, which makes sense. So, (D) works.
Quote:
I eliminated (E) as the meaning conveyed by the modifier "as the first birth...captivity" seemed wordy
The (E) version is busted in multiple ways.
The recent birth ... as the first birth ... took place in a Cincinnati zoo," doesn't convey a logical meaning. It seems to suggest that the birth took place in the zoo because it was the first such birth in over a century, which doesn't make sense.
Another issue with the (E) version is that "The recent birth ... took place in a Cincinnati zoo, a landmark development," misses the point to be made about the birth itself being a landmark development and conveys instead that the fact that the birth took place at a Cincinnati zoo is a landmark development.
