This choice results in a grammar error called a comma splice. \"Researcher Lin Zhi…silk\" and \"by dissolving…2 GPa\" are both independent clauses. They need to either be separated with punctuation like a period or a semicolon, or they need to be connected by a comma and a coordinating conjunction like \"and.\" A comma alone isn’t enough.

They need to either be separated with punctuation like a period or a semicolon, or they need to be connected by a comma and a coordinating conjunction like \"and.\" Choice C is incorrect. This choice results in a grammar error called a run-on sentence. \"Researcher Lin Zhi…silk\" and \"by dissolving…2 GPa\" are both independent clauses.
