Check the graphic below.
I agree with the OA. However, I don't understand a part of the OE:
In the explanation of the OA for the 2nd column, the OE mentions this:
"An employee would receive the lump-sum bonus on the birth of his/her first child only once. By comparison, the expected number of times an employee would receive the 10% raise - the benefit with the next highest instance cost - is 2 times in a 20-year career....)
Can someone explain the part highlighted in red?
Thanks

Hey,
They're just applying some probability to the logic.
If every year, 10% of employees are chosen for a raise, then an employee in any given year has a 1/10 chance of getting the raise.
So, in 20 years, an employee's number of raises would take on an expected value of 1/10 * 20 = 2; i.e, "2 times in a 20 year career".
Hope that clarifies.

Lowest F/C ratio means F must be less than C.
Option D will occur with very minimum frequency hence D is the correct option.
