Answer:
The correct answer is letter "C": following a component branding strategy.
Explanation:
The Brand Strategy is a plan to give value to a company by associating its name to a particular feature of the product or service the institution provides. The plan includes four (4) components: brand positioning, brand name selection, brand sponsorship, and brand development.
Brand sponsorship is the stage in which the company is in the capability of licensing its name to other businesses to spread its scope. Co-branding also takes place in this stage through partnerships.
Therefore, Dolby Digital is using the sponsorship component of brand strategy to spread its name in the market every time its logo is displayed before a film starts in a movie theater.
