Answer:
Option C is correct.
Step-by-step explanation:
The paycheck of a period is the time within which the initial investment is recovered.
It does not consider the time value of money, which means all cash flows have equal weightage.
The paycheck period is 5.6 years and it will not be affect by the change in the cash flow in the year 1 and 3.
The IRR (Internal return rate) and NPV ( Net present Value) of the project will get affected as these methods give more weightage to current flows than later.
Thus, increasing of year-1 cash flow decreasing of year-3 cash flow will increase the IRR and NPV of project.
Therefore, the correct answer is option C ( The IRR of the C will increase.)
