Answer:
A. The word Google has been added to the dictionary.
Step-by-step explanation:
Branding is way of giving special recognition to a company's products. Branding is important because it helps to differentiate a company's product from the competitors hence an essential marketing term.
For companies that want to create a brand in the market place, it is important that the company have a logo and products which are eye catchy, easily identifiable and can only be done by exerting energy on branding.
As in the scenario above, Google was added to the dictionary because of it's all time brand identity and household name status. Moreover, the company was not a successful brand initially but now exerted more effort towards branding hence came up with search engine which is now being used by all and sundry when it comes to internet searching.
