Final answer:
The statement that you must create a private app in the Shopify store to use tools like Slate or Theme Kit is true.
Therefore, the correct answer is: option a) True.
Step-by-step explanation:
To connect developer tools like Slate or Theme Kit with a Shopify store, creating a private app is required to provide secure API credentials.
When connecting these developer tools to Shopify, a private app provides the necessary API credentials, which allows the tools to interact with your store's data securely.
Using theme development tools such as Slate or Theme Kit requires access to the store's themes, which can be granted through the custom app's API credentials.
For example, in order to use Slate, you need to generate a set of API credentials and create a private app in Shopify. This allows Slate to authenticate and access the necessary resources in your store.
