Answer: b. No, because the state acted as a market participant
Step-by-step explanation:
The state in this instance was a market participant because they were acting as buyers who were looking for companies that could supply the service of exploiting their gas fields.
As a result, they have total discretion to pick whichever supplier they choose, regardless of the benefits or lack thereof, much like a normal buyer would do. The interstate company would therefore lose the case.
