What is the main purpose of the duplication detection filter in GitHub Copilot?

Suggested Answer: D Vote an answer

"GitHub Copilot has a duplication detection filter that checks suggestions of about 150 characters or longer against public code on GitHub. If a match is found, the suggestion is blocked if you have configured blocking." This clearly defines the purpose as preventing Copilot from suggesting verbatim code found publicly.
