Brecksen EOC Ethics Q 47

The answer to Q 47 regarding the use of logo on both letterhead and business card is confusing to me.

the answer explains that CFA logo is a certification mark indend to identify individual charteredholders and may not be incorporated into a company’s name or logo. It also says that the use of CFA logo is appropritate on the business card or letterhead of an individual cgarteredholder

Why is C not the correct answer?

I dont have the question in front of me, but if I remember correctly the person had used the CFA logo on the company letter head, which is not permitted.
