Answer:
B. Trademark
Step-by-step explanation:
A. A label is something giving information, in written format, about a company. The apple is not text, it is an image.
B. A trademark is like a logo in the sense that it is most often known as an image that helps you best recognize a company. That is what the apple is.
C. A generic name is the chemical name of a medicine. Apple is not a medicine company, it is a technology company.
D. A brand is the company. Apple is the company, but the apple (lowercase) is an image (which is why it is a trademark).
