Final answer:
Bliss's behavior of purchasing an expensive home security system based on her extensive watching of a horror television series demonstrates confirmation bias.
Step-by-step explanation:
The behavior exhibited by Bliss, who becomes convinced that she is likely to be victimized by a serial killer based on her extensive watching of horror television series and subsequently purchases an expensive home security system, is an example of confirmation bias.
Confirmation bias refers to the tendency to search for, interpret, favor, and recall information that confirms or supports one's prior beliefs. In this case, Bliss's belief that she is likely to be victimized by a serial killer is reinforced by the horror television series, leading her to purchase the home security system as a way of confirming her belief.
Therefore, the correct answer is b) confirmation bias.
