For displaying a banner on two different category pages with independent configurations by the merchant, Option C is the best approach. This code snippet uses the <iscontent> tag with a global context and specifies the object directly using pdict.ProductSearchResult.category. This approach ensures that the content is dynamically associated with the category being viewed, allowing for specific content configuration for each category page through the Business Manager. It provides flexibility and precise control over the content displayed on each category page, aligning with best practices for dynamic content display in Salesforce B2C Commerce.
