Explanation
A Change Set is the deployment solution that a consultant should use to deploy permission sets granting access to objects and fields from one of its sandboxes to Production. A Change Set is a collection of metadata components that can be deployed from one Salesforce org to another. A Change Set can be used to deploy permission sets, which are sets of permissions and settings that grant users access to various tools and functions in Salesforce.

Case teams in Salesforce allow for collaborative case management by enabling a group of users to work on cases together. By using case teams, Universal Containers can specify which users have access to cases based on the Product Type field. Additionally, workflow rules or process builders can be configured to send emails to case team members when a case is created or closed, ensuring that only those with access to the case are notified, thus meeting the requirements.
