Detailed Solution

We are given that the method is Census.
The statistical compilation of all units or members of the target population is the process used in the census method under the survey. So, in this case we relate the population to the entire set of observations connected to a particular study.
For example, if employees of an office have to give feedback on the staff faculty, the former will be held as the population of that study.
When we search for the advantages of census method, we need to remember two points:
1) Intensive nature of study: When we have to go for in-depth information, which is related to an issue. It will help us in all-inclusive understanding.
For example, in population census, other parameters like age, sex, marital status etc are also considered, apart from counting a number of people.
2) Accuracy and reliability of result: We know that the results are more reliable and accurate owing to the vast number of items that are taken into account.
So, a major merit of this method is the accuracy that is obtained by consulting each and every unit of the population, before drawing the results of the research. So, from the above two points and the given options, we have found that it does not rule out errors of sampling and reliability.
Therefore, the merits of the census method includes that it is accurate.
