Answer:
The correct answer is letter "D": The corporate tax rate increases.
Explanation:
In case the government decides to increase the corporate tax rates, companies will have to invest more in their production process so the output will be higher as long as the revenues so that extra profit could cushion the increase in the levies. However, if companies do not have enough reserves to invest, they are likely to request loans that will increment the firm's debt in the long run.
