Answer:
C. Informational
Step-by-step explanation:
As a manager at IBM, Danny uses the data about consumer preference on personal computer design to analyze consumer behaviour in relation to what they may like to purchase in future. This is essentially known as informational resource.
This is because Danny uses the raw data of previous purchases and/or polls to determine consumer behaviour. He deals mostly with information available to him and this is a form of data mining.
He analyses thus information to see if it confirms to recent market trends or not.
