The correct answer is telescopic alidade (option B) because when we do a plane table survey with the help of plane alidade we have to measure horizontal distances with tape or chain on the ground and then we plot them on our sheet with whatever scale we have choosen.
Hence, the correct answer should be option B. Telescopic alidade as option C and B we can directly eliminate.

I think the answer is telescopic alidade. As it helps us to sight both horizontal and vertical objects easily and it measures vertical angles from which we can measure vertical and horizontal distances is using trigonometric equations.
