Answer:
Dispositional attribution
Step-by-step explanation:
Dispositional attribution seeks to say that the reason for a person's behavior is due to internal behavioural characteristics of that person and not caused by external causes.
from the question, the reason Fiona is too busy to meet is external, that is she cannot meet because she is struggling to complete a task that is almost due. But Robert misunderstanding the situation ends up saying she did not meet with him out of arrogance which is an internal behavioural characteristic.
