GitHub Copilot for Business and Enterprise includes a policy setting at the organization level to manage suggestions that match public code. This feature, often referred to as the duplication detection filter, checks code suggestions against public code on GitHub. When enabled, it blocks any suggestion that is a verbatim match to publicly available code, thereby helping organizations avoid the unintentional use of such code snippets. This setting is specifically designed to address intellectual property and licensing concerns by preventing the introduction of code with potentially restrictive licenses.

A. GitHub Copilot Chat in the IDE: This is a feature for conversational interaction with Copilot, not a filter for inline code suggestions.

B. GitHub Copilot Chat in GitHub Mobile: This is the mobile version of the chat feature and does not control the filtering of code suggestions.

D. GitHub Copilot access to Bing: This setting allows Copilot Chat to use Bing search for more current information; it does not filter code suggestions against public repositories.

"Managing policies and features for Copilot in your organization." This document details the administrative settings for GitHub Copilot at the organization level.

Section: "Configuring suggestion matching policies"

Content: "GitHub Copilot includes a filter to detect code suggestions that match public code on GitHub. You can choose to enable or disable this filter for your organization... When the filter is enabled

GitHub Copilot checks code suggestions with their surrounding code of about 150 characters against public code on GitHub. If there is a match or a near match

the suggestion will not be shown to you." This directly supports option C as the correct mechanism.

2. GitHub Docs

"Using GitHub Copilot Chat in your IDE." This document describes the chat feature.

Section: "About GitHub Copilot Chat in your IDE"

Content: It explains that Copilot Chat is a conversational interface for coding-related tasks. This confirms that options A and B are features for user interaction

not administrative filters for suggestion sources.

3. GitHub Docs

"Managing policies for GitHub Copilot in your enterprise."

Section: "Enforcing a policy to manage use of GitHub Copilot's access to Bing"

Content: This section clarifies that the Bing access policy is specific to the Copilot Chat feature and its ability to perform web searches

which is distinct from the inline suggestion filtering mechanism. This confirms option D is incorrect.
