The correct answer is option C: "direct taping. " Direct taping is a method of linear measurement in which a tape measure is used to directly measure the length of an object.
This method is generally more accurate than tachometer or direct chaining, as it does not involve any calculations or estimations.

Techeometric survey is a optical method to obtain elevation angle with horizontal distance. And I think optical method is always gives better result than other method of measurements. So option A would be correct.

No, chaining and taping is not the same degree of accuracy in chaining max 1 in 1000 and degree of accuracy in taping max 1 in 100000 in case of inver tape.

In Direct taping, some corrections occur so it is not greater accuracy in linear measurements.

Invar tapes are used for greater accuracy by the survey of India and in geodetic surveys.
