You are a developer tasked with creating an admin management app for your Slack Enterprise...

A is the current technically correct answer, replacing the uploaded bank's marked C. Slack's current token taxonomy does not define an “Admin” token type. Slack officially distinguishes token types such as bot tokens, user tokens, workflow tokens, and configuration tokens. Administrative authority is expressed through admin.* OAuth scopes attached to a user token, rather than through a separate token type called “Admin.” For example, Slack's official documentation for admin.conversations:read, admin.apps:read, and related Admin API scopes explicitly lists the supported token type as User. To obtain a user token imbued with Admin API scopes, the application must be installed at the entire Enterprise organization level by an authorized Org Admin or Org Owner. The resulting user access token can then call the applicable admin.* methods. Creating, inviting members to, and archiving channels require the appropriate administrative conversation scopes, particularly admin.conversations:*, subject to the installer having the corresponding Channel Management permissions. Therefore, under current Slack documentation, User is the correct token type. “Admin token” is outdated/imprecise terminology because admin describes the permission scope, not a distinct token class. This maps directly to APIs for Managing Your Slack.
