The correct answer is: A. simple
The Search tool is a powerful tool that can be used to find information on a variety of topics. However, it is important to understand that the Search tool is best used when searching for simple data. This means that the data you are looking for should be relatively easy to find and should not require a lot of interpretation. For example, if you are looking for information
on the population of a country, the Search tool can be a great way to find this information. However, if you are looking for information on the history of a country, the Search tool may not be the best option, as this information is more complex and may require more interpretation.The other options are incorrect because they are not as relevant to the use of the Search tool. Option B, multiple data, is incorrect because the Search tool can be used to find multiple pieces of data. Option C, unique data, is incorrect because the Search tool can be used to find both unique and non-unique data. Option D, formatted data, is incorrect because the Search tool can be used to find both formatted and non-formatted data.
