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.

Sumit said:   7 years ago
But refraction error is only partially corrected not fully.

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.

As per my knowledge, reciprocal levelling eliminates both curvature and refraction error completely.
