If the chain line which runs along N-S direction is horizontal and the ground in E-W direction is sloping

ANS:D - it is possible to set offsets correctly on both sides.

Offset is the perpendicular distance taken from either side of the chain line running in a particular direction.

In our case, chain line runs along the N-S direction, so offset will be taken either right of N-S direction i.e. towards east side or left of N-S direction i.e.towards west side.
