fixed overheads volume

D is correct! (I don't know which book you found this is, but A is the wrong answer)

Can u please explain the same question bit more not just answer like how to solve it

The poster had solved in correctly which is why I didn't need to show the workings. They produced 300 units less than budgeted. Therefore the volume variance is 300 x 1.5 hours x $2.40 = $1,080 adverse Have you watched the free lectures on this?
