Which of these is an example of circular reasoning?

answer:

vampire knight

explanation:

its a two season anime series filmed in 2008, but the film production is great.   its dubbed in english, and has closed captions if that isn't good enough.   its very romantic and sort of weird when you find out who the main characters are at the end.   very very dramatic, but in a good way, and never gets old.   i've watched it over and over again but it still has not gotten old.   you'll love the night class.  

answer:

that is correct, but there is a fourth one, plasma.

explanation:

plasma is a state of matter that is often thought of as a subset of gases, but the two states behave very differently. but unlike ordinary gases, plasma is made up of atoms in which some or all of the electrons have been stripped away and positively charged nuclei, called ions, roam freely.
