If staff is not vertical, the reading will be too great. If staff is normal to the line of sight the value will be minimum or accurate. It will not be maximum. The intercept of staff increases when it is tilted away from normal and decreases or gets minimum when moved towards normal.

Staff intercept is the difference in reading between top and bottom cross hairs. If the staff is tilted forward or backward from normal, the staff intercept will increase. It is minimum when staff is truly vertical.

Thanks all for explaining the answer.

Reading will increase in both cases, if tilted away or towards. Because it's minimum when staff held normal. So you can't go below the minimum. So answer D is also correct but B is more logical.

If the staff is tilted away from the instrument intercept will be more n if staff is tilted towards the instrument the staff intercept will be minimum.

I think in both condition, value increase if staff tilted.

Since, staff is held inclined, cross hairs will intercept more readings than that of a vertically held staff in vertical direction.
