Answer:
The correct answer is option b.
Step-by-step explanation:
Shen is working in a country where the inflation rate is high.
He gets a salary every two weeks.
After receiving his salary he immediately goes out and buys all the goods he is going to need over the next two weeks.
He converts the remaining salary in a more stable currency.
He does this in order to prevent his salary from losing purchasing power.
This effort that he is making to prevent his real income from losing value is called the shoe-leather cost of inflation.
The shoe-leather cost can be defined as the cost of time and effort made to prevent the cash holdings from losing their value.
