First, we need to convert the mass of the piece of copper to grams per degree Celsius (g/°C) by dividing by its heat capacity:

mass/heat capacity = (218 g)/(83.9 J/°C) = 2.6 g/°C

Then, we can use the definition of specific heat, which is the heat energy required to raise the temperature of one gram of a substance by one degree Celsius:

specific heat = heat energy/(mass x change in temperature)

Since we are not given any change in temperature or heat energy, we cannot calculate the specific heat directly. However, we know that the units of specific heat are J/(g·°C), so we can convert our previous result to this unit:

2.6 g/°C x (1 J/1 g·°C) = 2.6 J/g·°C

Therefore, the specific heat of copper is 2.6 J/g·°C, which corresponds to choice A.
