${\text{(B) the unit must have comparatiblity}}$
${\text{(C) the unit must be simple and easily understandable in the process of inquiry}}$
${\text{(D) All of the above}}$

Answer 1

Hint: Here we have to conclude the given option by using the statement which is given in the question. Let us discuss the characteristics of statistical units and then select the relevant option.

Complete step by step solution:
Consider the first option which is that:
The unit must be standard and uniform.
A unit is standard when people all over a specific region or place use it to represent the data in that particular format. Data which is written in the standard format is easy to understand and to teach other people. When written in a standardized manner, multiple people who use the same unit won’t have any difficulty in understanding the particular unit. Uniformity of the unit is important because it should represent a specific quantity for a particular unit therefore option $(A)$ is correct.
Now, the second option is:
The unit must have comparability.
If the unit is standardized and uniform then it gets easy to compare with other values of the same unit. People who use the unit would be able to compare the values of multiple sources to effectively solve their problems in statistics. Therefore, in this case option $(B)$ is also correct.
And the third option is:
The unit must be simple and easily understandable in the process of enquiry.
If a unit is easy to understand by various people then the information the unit tries to teach will be easily understood by people too. This will help is making the unit more widespread and understandable by multiple people. This will result in ease of documentation and will result in less confusion.

Hence the correct option is $(D)$.

Note: There are also other characteristics of a statistical unit, some of them are:
A unit should not change with time, place and physical conditions, it should be of suitable size which is neither too big or too small etc.
