Correct Answer:
Option D —
No. because Gmail needs Internet access to contact its remote servers
Why this is the correct answer:
Gmail is a cloud-based email service. To send an email, your computer must communicate with Google's remote mail servers over the global Internet.
Since Riya’s office network is not connected to an ISP or the Internet, it functions purely as an isolated Local Area Network (LAN). While the computers in the office can talk to each other (for instance, sharing a local printer or a local shared folder), they have no pathway to reach external web servers like Google's.
Why the other options are incorrect:
A: Gmail does not have a "LAN cache" that automatically syncs across an isolated offline network to send external emails later.
B: Gmail does not care whether you use Wi-Fi or an Ethernet cable; it just requires an active internet connection.
C: Ethernet is simply a physical cabling and networking standard for connecting local devices. It does not provide "internal cloud routing" for external web applications without an Internet connection.
