Its either A or C... sorry dnt really know which 1 but m sure its one of these..
I believe it's answer choice C, Good luck!
.org, .gov, .edu are usually the most reliable domains when it comes to dealing with english related assignments.
.org - means the website is from an organization, without the intention of selling commercial products.
.gov - is from the government so we know that this is reliable
and .edu is usually for university websites.
Hope this helped.
