Option D is definitely the way to go. Reloading the firewall after adding the service is crucial to make the changes effective immediately.

I agree with Angella, D seems like the correct option for allowing access to the HTTPS port on a Linux system with firewalld enabled.

Hmm, option D looks like the correct answer to me. The firewall-cmd command allows you to add the HTTPS service permanently and reload the firewall configuration.

I think the answer is D, because it includes the --permanent flag to make the change persistent.
