Answer:
a. selective perception
Explanation:
Selective perception refers to only perceiving what an individual wants to, ignoring the viewpoint and ideas which oppose or challenge their own basis of perception.
In the given case, Donna who works in an audit firm was notified of the errors which as per her, she didn't commit. Instead of responding to such a mail or confronting the situation and explaining herself, she rather chose to ignore the mail altogether.
This classifies as a case for selective perception.
