Final answer:
Philip's response to Nancy's excitement about her grade was an example of disconfirmation, where he ignored her statement and shifted the conversation to his own needs. The correct answer is option: B. disconfirmation
Step-by-step explanation:
When Nancy told Philip, "I’m so stoked! I got an A on my chemistry midterm," and Philip replied with, "I’m hungry. Let’s get some lunch," Philip engaged in disconfirmation. Disconfirmation occurs when one person fails to acknowledge or validate another person's communication efforts or statements.
Instead of confirming Nancy's feelings of excitement about her academic achievement, Philip ignored her statement completely and shifted the focus to his own need for food. This kind of response can be perceived as dismissive and imply that what Nancy said was not important enough to warrant a response or acknowledgement.
