Which of the listed items will help you avoid duplicate content? Choose two answers.

A 301 redirect permanently moves a page from one URL to another, consolidating any SEO value and preventing duplicate content issues by ensuring search engines only index the new URL. The rel="canonical" tag tells search engines which version of a page is the preferred one to index, even if multiple URLs have similar content, effectively resolving duplicate content without requiring a redirect. The nofollow meta command prevents search engines from following links on a page, which doesn't directly address duplicate content. Implementing HTTPS encrypts website traffic and is crucial for security and rankings, but it doesn't solve duplicate content issues.
