(D) pig fly
It shows the action which is being done upon the subject of the sentence which is the pig.
I would say the bet answer would be option D "Five-year-olds will be evaluated." This would set the stories setting as a dystopia because no five year old would be evaluated at such a young age and given a job. Tommy was also worried that his creativity, and intelligence would go unnoticed and he would be placed as a coal processor and hoped he would become a scientist or a programmer. Also, remember that a dystopia is a made up world of injustice and suffering.
Hope this helps.
