What functionality does the Shopify Theme Store provide?

The Shopify Theme Store primarily functions as a marketplace where users can browse, purchase, and install themes designed for their online shops. This platform offers a diverse selection of both free and paid themes, catering to various styles and business needs. Customers can preview themes, read reviews, and see detailed descriptions before making a purchase, ensuring they choose the best fit for their brand.

The option that suggests users can develop their own themes is not directly aligned with the core functionality of the Theme Store; while developers can create themes for submission to the store, the store itself is not a development platform. Additionally, limiting users to only browsing free themes overlooks the availability of a wide range of paid themes as well. Finally, while users can sell their themes to other merchants, this describes the process for developers rather than the general functionality provided to all users by the Theme Store. Therefore, the correct answer focuses on the comprehensive capabilities of browsing, purchasing, and installing themes, which is the primary purpose of the Shopify Theme Store.
