Final answer:
The correct option is c. Data-driven ads.
For an athletic shoe company looking to deliver country-specific ads accurately, data-driven ads are the most suitable format due to their location targeting capabilities.
Step-by-step explanation:
To ensure that your athletic shoe company's ad creative for each country is viewed correctly, the most suitable ad format would be data-driven ads. This type of advertising utilizes user data to deliver personalized ad experiences to the target audience, which can include location-specific content.
Data-driven ads are capable of ensuring that viewers in different countries see the appropriate ads that are relevant to their region. This technique aligns well with your company's goal of funding sporting events in multiple countries and aiming to deliver country-specific content.
In-stream video ads could also be a choice but are generally less targeted compared to data-driven ads. Native ads and responsive ads do not inherently target based on location, hence they might not guarantee the geographical specificity required by your company. Therefore, data-driven ads' ability to target viewers based on their location and possibly other pertinent factors makes them the optimal choice for your advertising needs.
