Answer 2

The first sentence is not properly punctuated. The third and the fourth sentences as well. The only sentence with the correct punctuation is the second sentence.  A semicolon is used to join two complete sentences with related ideas. The second sentence is actually made up of two related sentences joined by the semicolon.
