In order to have interference fit, it is essential that the lower limit of the shaft should be

1. greater than the upper limit of the hole
2. lesser than the upper limit of the hole
3. greater than the lower limit of the hole
4. lesser than the lower limit of the hole

For making interference fit, seeing the figure it is essential that lower limit of shaft should be greater than upper limit of hole.
