Why one should not go for sampling? It is less costly to administer than a census The person authorising the study is comfortable with the sample. Because the research process is sometimes destructive None of the above

The question seems to be asking for reasons why one might choose not to use sampling in a study. Here are potential answers based on the options provided:

1. "It is less costly to administer than a census": This is actually a reason why one might choose to use sampling, not a reason to avoid it. Sampling is often used because it is less expensive and time-consuming than studying an entire population (census).

2. "The person authorising the study is comfortable with the sample": Again, this seems like a reason why one might choose to use sampling. If the person authorising the study is comfortable with the sample, then there is no reason not to use it.

3. "Because the research process is sometimes destructive": This could be a valid reason to avoid sampling. If the research process involves destructive testing or if studying the sample could harm the population in some way, then it might be better to avoid sampling.

4. "None of the above": This could be the correct answer if none of the other options are valid reasons to avoid sampling.

Without more context, it's difficult to determine the correct answer. However, based on the information provided, the most likely answer seems to be "Because the research process is sometimes destructive".
