Answer:
A) both the price level and real GDP fall
Step-by-step explanation:
During recessions both the inflation rate (change in general price level) and the real GDP will either stop growing or reduce their growth rate.
Recessions are usually the result of financial crisis, especially the last great recession of 2008 through 2010. Once private consumption starts to fall, the whole economy will slow down dramatically or also fall. Private consumption represents almost 70% of the GDP, so it is by far the largest and most important economic factor.
