Answer:
Because the meat packing industry was growing, the demand for cattle went up.
Explanation:
The sentence that uses a subordinating conjunction correctly is: "Because the meat packing industry was growing, the demand for cattle went up."
This option is correct because it uses "Because" and correctly places the "comma" in the sentence. The subordinating conjunction, "Because" introduces the dependent clause.
Subordinating conjunction is a word that joins a dependent clause and an independent clause. It usually signals a cause-and-effect relationship or shift in time between two clauses. Some examples of subordinating conjunction are: by the time, till, until, though, now that, once, since, when, whenever, although, even though, who, whoever, whom, etc.
