ANS:D - indefinite features to be surveyed.

Here the limiting length of offset are affect accuracy and mtd of setting out and scale of the plotting only. The limiting length of offset depend upon the 1-scale of plotting 2. Possible error in direction and length 3. Accuracy desired. It is the maximum length of an offset for survey work due to which no error is reflected on map.
Max Length of error allowed on paper =0. 025cm.
