The D. Company Name most likely stands out on a business card with an address or such in smaller font below. A logo does nothing for a business card if a potential customer doesn't even know the name of the business. While logo's are often present on a business card, the company name is far more crucial to enunciate clearly which is of course, important for business's attraction of new customers.
So D. Company Name is my final answer!
Hope this helps! ;)
