While sending e-mails, which option should be chosen if you want to put another person in a copy secretly?

When sending emails and you want to secretly copy another person, you should choose the "Bcc" option, which stands for "Blind Carbon Copy". Here are the steps:

1. Open your email client or service.
2. Click on the option to compose a new email.
3. In the new email window, you will see fields for the recipient's email address, usually labeled "To".
4. There will also be fields labeled "Cc" and "Bcc". If you don't see the "Bcc" field, there might be a button or option to show it. In Gmail, for example, you can find it by clicking on the "Cc" field.
5. Enter the email address of the person you want to secretly copy in the "Bcc" field.
6. Compose your email and send it. The person in the "Bcc" field will receive the email, but their address will not be visible to the other recipients.
