In Q40, the questions just mentions the “arc”. So I marked D because by default I decided to take the minor arc (as it was a single choice only) however if we consider the major arc then the answer is A -

4.pi < 2.pi.d/3 < 6.pi
6 < d < 9

So is this an error by Manhattan and ETS is not expected to make this error.
Or
Is there something that I missed?
