Final answer:
The correct answer is option b, indicating that section files cannot be loaded using conditional logic, while snippets can be. Sections are elements customizable via the theme editor, and snippets are reusable code chunks.
Step-by-step explanation:
The difference between sections and snippets lies in how they handle loading and access to variables within Shopify theme development. Option b is correct: Section files cannot be loaded using conditional logic, while snippets can be loaded using conditional logic. Sections are versatile, predefined elements that can be customized within the theme editor and used multiple times, while snippets are chunks of code that can be included in other theme files using the {% include %} tag. Snippets are helpful for repeating sections of code across multiple pages without the need for duplication. It's important to note that both sections and snippets have access to global objects, however, sections cannot be loaded conditionally straight out of the box - they are typically loaded as part of the theme's layout. Custom logic would need to be implemented for conditional loading of sections.
