Staff is a leveling instrument on which reading is taken in the form of RL.

What about intercept?
Jeevitha said:

Intercept of staff is the distance between top and bottom staff reading.

Where am I suppose to take the reading on the staff when I want the direction CL when using a theodolite.
SADASIVUNI said:

Answer is C because the staff reading will decrease.

What is RL?
Aman said:

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 norman and decreases or gets minimum when moved towards normal.

Staff intercept is differ between length of top and bottom crosshair in the instrument (say S1 and S3). Google "tacheometry" and just see the image you'll get everything.

Why not an option D?

Option D is incorrect because the intercept rather decreases if you tilt the staff towards making it normal to the line of sight.
