Answer:
a. Router
Explanation:
The device that provides emails to the laptop would be the Router. This device is basically the intermediary between your personal computer and the vast internet. It basically decides what information is safe enough to allow into your computer, as well as what the fastest path for the data to travel is. When emails are sent to your address the router allows you to access that information by connecting you to the correct pathways through the internet so that you can view those emails.
