Asset allocation decisions - CFAI Practice Asset Allocation Q59

Hi everyone,
I’m struggling to understand why statement B is incorrect.
Can anyone help explain why?
Thanks!




C is the correct answer.

Why should B be the ‘most appropriate’ answer? Current asset allocation and Option 1 for defined benefit plan shows 10% allocation to real estate. So, there is no change in real estate allocation.

Questions does not clearly mention the benefit out of land. But, it clearly says that 30% of the income is from Africa. So, when African equity is in bad shape, asset under pension plan will be of lower value. To fill the gap, company would require to add funds into pension plan. And, they will not be able to do so because African economy will be in bad shape too and company’s income may be negative.

This question seems like it is from Fixed Income but it is actually using the concept from Portfolio Management and Private Wealth Management. .
