Answer:
Option B. Considered sunk costs, not relevant in further decision making
Step-by-step explanation:
The reason is that the past costs are not relevant costs for future opportunities as it does not qualifies following conditions except that it was cash flow in nature:
- Cash flow
- Future related
- Differential
So the cost that doesn't qualifies all of the three conditions are not considered relevant for decision making and is deemed sunk cost for future decision making process, which means it is not considered.
So the option B is correct.
