The chart shows the bids provided by four engineers to test a prototype. Which is best supported by the information in the chart?

A Jin is less cost-effective than Greg because he charges more per day than Greg.
B Zoe is more cost-effective than Orion because she takes less time to complete the project.
C Jin is the least cost-effective because he charges the most per day.
D Greg is the least cost-effective because he charges the most for the project.

D

Greg is the least cost-effective because he charges the most for the project.
