Question

mr stevens has the following email address: mrstevens@mail.net. which part of this email address identifies the internet service provider (isp) through which you can access his email? a mrstevens@mail.net b .net c mail.net d mrstevens@

Explanation:

In an email address like username@domain.extension, the domain part after the @ symbol (mail.net in this case) is related to the server where the email is hosted. While it doesn't directly identify the ISP, it is part of the infrastructure used to access the email. The top - level domain (.net) is just a classification of the domain type and not the ISP. The username part (mrstevens) is for identifying the user. So the part that is most relevant to the infrastructure through which the email can be accessed is the domain name mail.net.

Answer:

C. mail.net
