Slack's recommendation for secure external collaboration is:
"Single-Channel Guests are ideal for providing external users with access to only one channel, maintaining strict control over permissions and access."
Multi-Channel Guests (B, C) grant access to multiple channels, which is unnecessary and riskier. Creating a new workspace (A) adds administrative burden and is unnecessary for one project.
