What describes the portion of one year's GDP that must be sacrificed to reduce inflation by 1 percentage point?

The main idea here is the sacrifice ratio for disinflation—the trade-off between reducing inflation and losing real GDP in the process. It is defined as the portion of one year’s GDP that must be sacrificed to lower inflation by one percentage point. This directly quantifies the cost of bringing inflation down: how much output we give up for each percentage-point drop in inflation. So the option that states the exact description—what fraction of annual GDP must be sacrificed per 1 percentage point fall in inflation—best captures this concept. The other choices describe related ideas (unemployment during tightening, the growth rate required to achieve a given inflation drop) or name the concept, but they don’t as directly define the measured trade-off.
