Which of the following is not a type of chain?
Metric
Gunter
Steel band
None of the above
None of the above
In surveying, various types of chains are used for linear measurement, including the Metric chain, Gunter's chain, Engineer's chain, Revenue chain, and Steel band ┬╖ Since Metric, Gunter, and Steel band are all valid categories of equipment used in chain surveying, none of these options represent an incorrect type.

Chains operate on the principle of discrete link-based measurement or continuous ribbon measurement ┬╖ The physical length of the chain, calibrated under standard tension and temperature, is laid out along the survey line, and marks or pins are used to record the distance covered.
Metric chains are standard in India, usually available in 20m and 30m lengths.
Gunter's chain, also called Surveyor's chain, is 66 feet long and divided into 100 links.
Steel bands are highly accurate compared to link chains as they are less susceptible to elongation or link wear.
Revenue chains are typically 33 feet long and used primarily for cadastral surveys.
Simple and easy to use in the field.
Does not require complex calculations or electronic power.
Prone to errors due to temperature expansion or mechanical link wear.
Heavy to carry and cumbersome for long-distance measurements.
Measuring land boundaries.
General survey work for civil engineering projects.
A link in a 20m chain is exactly 20cm long.
The steel band is a thin strip of steel, usually 20m, 30m, 50m, or 100m long, stored in a metallic case.
D is correct тАФ All options listed (Metric, Gunter, and Steel band) are standard types of equipment used in surveying.
Remember that 1 Gunter's chain is equal to 10 square chains in 1 acre; this is a common conversion factor asked in competitive exams.
