   A developer is building a custom integration that uses OCAPI data endpoints to retrieve a list of all products from a B2C Commerce instance. The product catalog contains over 10,000 products. The developer needs to ensure the integration retrieves the complete list without missing any records. What is the most appropriate way to handle this?

   • AMake a single GET request to the product endpoint and rely on the default response size.
   • BUse the `expand` parameter to include all related data, which will also bypass the pagination limit.
   • CSet the `count` parameter to a very high number, such as 100,000, to retrieve all products in one request.
   • DUse the `start` and `count` parameters to paginate through the results, iterating until all products are retrieved.
