Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
A theodolite is a precision surveying instrument used for measuring horizontal and vertical angles.
Common operations associated with a theodolite include:
• Transiting (plunging).
• Face left and face right observations.
• Right swing and left swing of the telescope. Gauging and sounding are operations related to hydraulic engineering and hydrographic surveying, not to theodolite operation.
Step 1: Examine the given terms. The first three options represent standard theodolite operations. The terms "gauging" and "sounding" are unrelated to theodolite use.
Step 2: Identify the unrelated terms. Hence, \[ \boxed{\text{Gauging and sounding do not relate to the operation of a theodolite}.} \] Therefore, the correct option is \[ \boxed{(D)\;\text{Gauging and sounding}.} \]
