Answer:
.b. it forces firms to internalize the external cost of emissions
Explanation:
 A carbon tax is a fee imposed by the government on any firm that burns fossil fuels. Fossils most used by firms include gasoline, coal, oil, and natural gases. Burning of these fossils emits greenhouses gases such as carbon dioxide and methane, which creates global warming by heating the atmosphere. 
A carbon tax forces enterprises to pay for the harsh effects of global warming on society.  If the tax is set at a high rate, it deters firms from burning fossils.  Companies adopt environmentally friendly production processes to avoid the carbon tax. 
 
        
             
        
        
        
The maturity risk premium on the 2-year Treasury security is C. 1.39%
Using this formula
rd = r* + IP + MRP
Where
rd represent Required rate of return on 2-year Treasury Security = 6 75%
r* represent real risk free return = 3.18%
IP represent Inflation Premium = 2.18%
MRP represent Maturity Risk Premium
Let plug in the formula
6.75% = 3.18% + 2.18% + MPR
6.75%=5.36%
MRP=6.75% -5.36%
MRP = 1.39%
Inconclusion the maturity risk premium on the 2-year Treasury security is C. 1.39%.
