Live wire, is an energetic person while a bright spark is a clever or witty person so they are both terms for people. So the answer is A for the first question.
In the second question, you can think of the front and back in 2 ways, the front does not necessarily mean the first one of the page. What if the front started at the other side. That will leave you with L and K you can arrange them in different orders and they will work.
