The actor is out of jail, and not exactly a free man, since he will be under house arrest for an additional 90 days.

The correct answer is option number -A

As the 1st part of the sentence tells that actor will be out of jail(positive side),whereas 2nd part tells the negative side that he will be under house arrest.

We join sentence by `and' to connect it.

When both the parts of the sentence concludes the same meaning.

But we use to show indifference, contradiction.

Though and if -doesnt add any meaning to the sentence.
