The correct answer is C.
A decrease in consumer spending means a decrease in the aggregate demand levels and, in consequence, in total output and in the employment figures. Therefore, the economy is experiencing a contraction.
In order to reverse the trend, a discretionary spending budget can be implemented. Investing public money would boost aggregate demand levels and create job positions. These new workers will start to earn a salary, increase their income available and start to demand more goods and service, therefore expanding aggregate demand even further. Therefore, the economy will start to grow again.
