Answer:
The correct answer is Brand Extension.
Step-by-step explanation:
When a company launches a new product with an existing brand name, this is called as a brand extension.
We can understand this concept by taking an example. Suppose there is a company, say Honda. There different products of the same company. In the last few years, Honda has launched many products. Honda cars, Honda Generators, Honda Lawnmowers, Honda Snow throwers, Honda Water Pumps, etc. These all products are launched under the same logo and trademark, 'Honda'. So this is called the Product Extension.
