Which of the following is an independent clause?
A
After going to the store,
B
Because Bernadette had a lot of shopping to do,
Before Bernadette went to the store.
D
Bernadette jogged to the corner store.
it wouldnt make since if it was A because it's not a complete thought. B is a dependent clause because it depends on a different part of the sentence. As for D it can exist as it's own sentence.
