Answer: Option 'a' is correct.
Explanation:
As we know that
Nominal wage is the value of wage in dollars that a particular person gets, whereas the real wage is the value of wage he is actually used that shows the purchasing power of a particular person.
If the wage is increased by 3%, and the inflation is increased by 6%.
Then, the nominal wage has increased but real wage decreased due to increase in inflation.
Hence, option 'a' is correct.
