which sentence correctly used punctuation with a subordinating conjunction?

Question

Because you offered to help.
Because of you, I was able to get the help I needed.
You came over: because I needed some help.
I got the help I needed; because I needed some help.

Answer 1

The sentence that correctly uses punctuation with a subordinating conjunction is:

Because of you, I was able to get the help I needed.

In this sentence, the subordinating conjunction "because" is appropriately followed by a comma to separate the dependent clause from the independent clause.
