Error due to earth curvature is partially eliminated other boths are fully eliminated.

No, in reciprocal levelling error due to earth curvature and refraction is completely eliminated.

Rishabh said:   6 years ago
Yes, D is the right answer.

Refraction is a partly eliminated.

The right answer is parallax. But it is not in options.

Kirti said:   7 years ago
It is due to the reciprocal levelling elimination errors due refraction, curvature and collimation.

Sukla said:   7 years ago
D is the right answer.

Ankush said:   7 years ago
Refraction is not right. D option may right.

Sourish said:   7 years ago
D is the right answer.

It eliminates error due to Refraction, Curvature and due to collimation.
