Explanation:

The word "their" is a possessive pronoun, while the correct word here should be "there" which is used to indicate the existence of something. The comma after "key" is appropriate as it separates the dependent clause from the main - clause, and inserting a comma after "line" is not necessary.

B. replace their with there
