Which of the following websites would most likely be a biased source for research about the effects of television on children?
A. a site run by an association of children's physicians.
B. a site run by a cable television network.
C. a site run by a teacher.
D. a site run by a parent group.

I think the answer is B. because the cable company is not going to want a bad reputation so they will use bias to make themselves sound good.
but I'm not 100% sure
