The correct answer is that a Google Cloud project can reserve a maximum of 5 static IP addresses per region. This limit applies to both standard and ephemeral IP addresses.

The reasoning behind this limitation is tied to resource management and efficient allocation within Google Cloud's infrastructure. By restricting the number of static IP addresses per region, Google Cloud ensures that resources are used optimally and prevents depletion of IP addresses, which can arise if users reserve large quantities for projects that do not require them.

This design encourages best practices in architectural design and IP address management. For those needing more than 5 static IP addresses in a single region, it is possible to work around this by creating additional projects; each project can independently reserve up to 5 static IPs within the same region, thus allowing for scalability while adhering to the limits imposed per project.
