2018 PM Mock q60

Is there something wrong with this question or is my understanding wrong? The way I understand the question is which item is not an error. And both A and B are correct presentations. C is an incomplete presentation. So the way the question is asked, I cannot see how A is a correct answer.

Can someone clarify this for me pls?

The answer is worded amazingly poorly, to the point of being incomprehensible. Here’s the scoop:

A is the composite % of firm assets. This is correct.

B is Note 3. B is NOT correct because you need to say that policies for calculating returns are available on request, and it doesn’t mention that. Yes, that is how picky they are being.

C is standard deviation. C is NOT correct because you need to show standard deviation of the benchmark, not just the composite.

So the answer is A.
