How can you create a link that opens in a new tab?

To create a link that opens in a new tab, using target="_blank" is the appropriate method. The target attribute specifies where to open the linked document; when set to "_blank," it instructs the browser to open the link in a new tab or window. This is a standard practice in HTML for ensuring that users can easily return to the original page after viewing the linked content.

Adding rel="noopener" is a security measure often used in conjunction with target="_blank" to prevent a newly opened page from having control over the original page via the window.opener property. While it enhances security, it does not influence the functionality of opening the link in a new tab itself.

Using target="_new" is not a standard value as recognized by HTML specifications. Browsers may not consistently support this value for opening links in new tabs, making it an unconventional approach.

The attribute open="new" is not a recognized HTML attribute for links and will not have any impact on link behavior. Therefore, among the provided options, target="_blank" is the only one that correctly accomplishes the task of opening a link in a new tab.
