Correct Answer is H
Explanation
Item H: The underlined part is a complete sentence before and after, so the period needs to be broken.
Item F: It is an attributive clause, that should act as the subject or object in the clause, and the clause does not lack the subject or object, so it is wrong.
Item G: Two complete sentences are connected by and, which need to be connected by ", and", so G is wrong.
