Which sentence begins with an independent clause and ends with a dependent clause (1 point pick one)

O AJ can run faster than anyone
O Because it is my birthday, my mom made a cake
O Sarah is good at math because she studies.
O Besides math, I enjoy science

O Because it is my birthday, my mom made a cake

Is that correct?

I apologize for the confusion. Actually, none of the sentences provided begin with an independent clause and end with a dependent clause.
