Confirmatory bias refers to:

a. when a specific suspect has been fixated upon and investigators ignore other possibilities.

b. none of these describe the concept.

c. when a confirmation of racial bias is pending.

d. when it is confirmed that the prosecution is biased against the suspect.

I think the right answer is a. when a specific suspect has been fixated upon and investigators ignore other possibilities. A bias is a deviation of the thought that causes us to have an erroneous judgment or an irrational interpretation of the events. The confirmation bias occurs when we ignore other evidence of an event to confirm an assumption we have, although this conclusion will be wrong.
