Answer:
C. Anchoring
Step-by-step explanation:
The first price to be mentioned will have an effect on the perception of all future prices. If we start with $200, then $100 will seem cheap, but £1000 seem expensive. But if we start with $10, then $100 will seem expensive.
The anchor for a price perception may be found in the first price mentioned. It can also arrive in the mind of the purchaser, where the anchor may have been set by previous experience.
