Answer

The option that connects the dependent clause to the independent clause using a comma is correct.
The correct option correctly uses a comma to attach the dependent clause starting with 'although' to the preceding independent clause, resolving the fragment and creating a single, grammatically correct sentence.

Step-by-Step Solution

1
Analyze the underlined portion and the sentence structure.
The clause 'Although it remained unknown to the Western world...' starts with a subordinating conjunction and cannot stand alone as a complete sentence.
A dependent clause must be joined to an independent clause to avoid creating a sentence fragment.
2
Select the punctuation that correctly connects the dependent clause to the preceding independent clause.
A comma is the correct punctuation to attach an ending dependent clause to an independent clause.
Using a period or a semicolon isolates the dependent clause, causing a fragment, while removing the subordinating conjunction without a coordinating conjunction creates a comma splice.

Key Concept

Correcting sentence fragments by properly connecting dependent clauses to independent clauses.
