Answer and Explanation:
Cleft sentences are used to connect something previously understood to new information or to emphasize something by placing it in a different clause. When we use this type of structure, we are basically dividing a piece of information into two clauses. It is common to use <em>it</em> or <em>wh-</em> words to form the cleft sentence.
1. I don't like a manager who acts like a tyrant. = What I don't like is a manager who acts like a tyrant.
2. We're looking for someone who is a team player. - What we are looking for is someone who is a team player.
3. He would prefer to walk to the theater. - What he would prefer is to walk to the theater.
4. She wrote the most popular mystery novel of the year. - It was she who wrote the most popular mystery novel of the year. / What she wrote was the most popular mystery novel of the year.
5. We saw the most dangerous snake in the world. - What we saw was the most dangerous snake in the world. / It was the most dangerous snake in the world that we saw.

the 3rd option is the correct answer
I would have to say that the best way to revise sentence four is by changing "aren't" and "they're" to "are not" and "they are."
"Argue" works better than "fight."
Deleting the entire sentence would remove the transition into cost efficiency of the tablets.
And moving the sentence to the end would place the transition to cost efficiency in the wrong place.
