answer: A. site ends in ".edu
explanation: Based on the answer choices you've given me in the ask for details, i'd go for A. site ends in ".edu". sites that end in ".edu and .gov" are usually only handed out by the government, so you know they are reliable sources of information. if a website has spelling errors or no sources cited, the website is probably unprofessional, so that knocks off b and d. and if there's no info about the author, you won't know if the information is reliable since the person could be a trained professional in the topic area, or somebody giving false info. this knocks off c, so a would be your best answer.
