Although Sue Ann had grown up in a sheltered environment, but she quickly adapted to life in New York City

Although Sue Ann had grown up in a sheltered environment, she quickly adapted to life in New York City.

Explanation:

Punctuation in grammar is one major issue in writing and using English correctly. And with that, it is also a must to know when, how and which punctuation forms to use accordingly.

In the given sentence, we have two parts of the sentence, "Although Sue Ann had grown up in a sheltered environment" and "but she quickly adapted to life in New York City". And the use of the subordinating conjunction "although" introduces the subordinate clause for the given sentence. And with conjunctions, if subordinate conjunction is used, then there is no need for coordinating conjunction in the same sentence. For it will make the sentence grammatically incorrect.

Thus, the final correct sentence will be-

Although Sue Ann had grown up in a sheltered environment, she quickly adapted to life in New York City.
