Answer:
Option E (a and d), is the right answer.
Step-by-step explanation:
Option E is the correct answer because increasing aggregate demand results in increasing income, output, and employment. In an economy, when the aggregate demand increases, the price level also goes up. Due to the rise in aggregate demand the aggregate demand curve shifts rightwards. Consequently, it shows that there will be an increase in the gross domestic product in the short run. That is why option E is correct.
