Answer:
A. Making the promise in public will make it harder to back out of the deal.
Explanation:
Suzanne Collin's "The Hunger Games" series revolves around a dystopian world where 'volunteers' from the different districts of the society's poorer sections fight for their district's resources. These 'tributes' were made to fight it out in a televised reality show for the entertainment of the higher, richer people in the Capitol.
In chapter 3 of "Mockingjay", Katniss decided to propose some demands of her own if she is to become the Mockingjay. The demands vary from safety to their cat, Buttercup, the right to hunt alone with Gale, and also some immunity promise to Peeta. She wanted President Coin to make these promises in public so that there'll be no chance to back down on those promises.
Thus, the correct answer is option A.
