- Using the Cloud SQL Auth proxy is a recommended method for secure connections, especially when dealing with dynamic IP addresses. - The Auth proxy provides secure access to your Cloud SQL instance without the need for Authorized Networks or managing IP addresses. - It works by encapsulating database traffic and forwarding it through a secure tunnel, using Google's IAM for authentication. - Leaving the Authorized Networks empty means you're not allowing any direct connections based on IP addresses, relying entirely on the Auth proxy for secure connectivity. This is a secure and flexible solution, especially for applications with dynamic IPs.

In question "You want to use Cloud SQL public IP", how this could be if "Leaving the Authorized Networks empty means you're not allowing any direct connections based on IP addresses" ?

Links also say not to go with option D. 0.0.0.0/0 which includes all possible IP Addresses is not recommended for security reasons. You have to keep access as restricted as possible.
