It is generally considered safe to use public Wi-Fi hotspots if you are connected to:

Internet server
ISP
VPN provider
All of the above

The correct answer is: VPN provider

Using a VPN provider while connected to public Wi-Fi hotspots is widely recognized as a safe practice because VPNs (Virtual Private Networks) create a secure, encrypted tunnel between your device and the internet. This encryption protects your data from potential eavesdroppers who might be using the same public network. When you connect to a public Wi-Fi hotspot without a VPN, your data can be intercepted more easily, making it vulnerable to hackers. In contrast, connecting solely to an internet server or relying on an Internet Service Provider (ISP) will not provide the same level of security. While these connections facilitate internet access, they do not inherently encrypt your data, nor do they offer the same privacy benefits that a VPN does. Thus, using a VPN while accessing public Wi-Fi helps safeguard your personal information, making it the correct choice in this scenario.
