Direct chaining and direct taping both are same.

Mirun Lal said: (Jan 15, 2018)  
Yes, direct taping and chaining are same.

Bani said: (Sep 23, 2018)  
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.

Pavani said: (Nov 11, 2018)  
In Direct taping, some corrections occur so it is not greater accuracy in linear measurements.

Raji said: (Oct 22, 2019)  
Invar tapes are used for greater accuracy by the survey of India and in geodetic surveys.

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.
