In Salesforce, the Contacts object is used to store information about individuals associated with an Account (e.g., the customer organization). Since the new Director of IT works for Northern Trail Outfitters (NTO), the correct place to store their information is under Contacts, linked to the relevant Account.
* A. Accounts: Used for organizations or companies, not individuals.
* C. Leads: Used for prospective customers or individuals before they are qualified as contacts.

Explanation
The best way to create a field that shows the amount as described in the question is to use a bucket field off of Amount. A bucket field lets you group report values into categories without creating a formula or a custom field2. You can create a bucket field for any numeric, picklist, or text field in a report.

The place where the employee should update their name and email address changes is the User Record page from Setup. The User Record page is where the employee can view and edit their personal information, such as name, email, username, alias, and profile. The employee can access the User Record page by clicking on their profile icon and then clicking Settings. Then, they can click on Personal Information under My Personal Information and edit their name and email address. The User Profile page is where the employee can view and edit their profile picture, about me, title, and contact information, but not their name and email address. The Contact Record page is where the employee can view and edit their contact details, such as phone, address, and social media accounts, but not their name and email address.
