A company maintains a REST service using Amazon API Gateway and the API Gateway native API key validation. The company recently launched a new registration page, which allows users to sign up for the service. The registration page creates a new API key using CreateApiKey and sends the new key to the user.
When the user attempts to call the API using this key, the user receives a 403 Forbidden error. Existing users are unaffected and can still call the API.
What code updates will grant these new users access to the API?

• A.The createDeployment method must be called so the API can be redeployed to include the newly created API key.
• B.The importApiKeys method must be called to import all newly created API keys into the current stage of the API.
• C.The updateAuthorizer method must be called to update the API's authorizer to include the newly created API key.
• D.The createUsagePlanKey method must be called to associate the newly created API key with the correct usage plan.
