What happens when you click a hyperlink for an email address?

A web browser searches for the individual who has that email address.
Word creates a new document with that email address as the file name.
An email program automatically sends a test message to that email address.
An email program opens with a new message to be sent to that email address.

When you click a hyperlink for an email address, an email program will get open with a new message to be sent to that email address

Explanation:

You you click on an email hyperlink in which an email address is embedded. A default email management program for example outlook etc will get open with a new message windows to be sent to that email address.

Other options are not correct, because when you will click on email hyperlink, it will always open email program with a new message on your system. It will not open word processing documents and automatically send a test message to user.

since it can be assumed that what aslam is making is a template by compiling all the commonly used excel formatting in several worksheets in an excel document, aslam can choose to save it using the .xltx or .xltm format instead. thus, aslam can distribute the templates he has made to his team members in an easier manner.

i do not get the question.
