The correct answer is c.
After the Battle of the Black Hills, General George Washington came up with the idea of moving his camp to a place that would allow him to survive the winter. So he chose Valley Forge, Pennsylvania. This place was close to the British, which allowed them to watch and allowed to get food in Pennsylvania.
During the stay in Valley Forge many soldiers died due to diseases and infections. Their clothes were not adequate to survive the winter and they were very badly fed. This catastrophe was solved with the arrival of the women and the children of the soldiers, since they were in charge of caring for them, curing them, washing and fixing their clothes, etc.
The soldiers in the camp received intense military training and the support of their families. This allowed the American Army to get out of there stronger, prouder and better trained.
