The correct answer is Ask the site administrator to create a shareable Confluence invite link.

Ask the site administrator to create a shareable Confluence invite link lets the site administrator generate a join link that prospective team members can use to sign up without waiting for per user approval. The administrator can attach Confluence product access and appropriate permissions to those who join so the invited users can create pages and add comments.

Ask the Confluence administrator to enable anonymous viewing of public spaces is incorrect because anonymous viewing only allows read access and does not permit creating pages or adding comments. That option does not meet the requirement for invited users to have authoring and commenting rights.

Ask the site admin to change the site 'User invites' policy to 'Invite anyone' for Confluence is incorrect because that policy change governs who can send invites or which users may be invited and not a mechanism to let users join immediately with assigned Confluence access. It does not by itself provide a sign up link that grants the needed product permissions.

Request that the site admin configure an approved domain invite for Confluence is incorrect because allowing an approved domain controls sign ups by email domain and usually requires organization domain management. It does not directly provide a public shareable link for immediate sign up with preset authoring and commenting permissions.
