The correct answer is C. Representative to the population.
A representative sample is a subset of a population that accurately reflects the population as a whole. This means that the sample should have the same distribution of characteristics as the population, such as age, gender, race, and ethnicity.
A random sample is a sample in which every member of the population has an equal chance of being selected. This is the most accurate type of sample, but it can be difficult and expensive to obtain.
A quota sample is a sample in which the researcher selects a certain number of people from each group in the population. This type of sample is less accurate than a random sample, but it is easier and less expensive to obtain.
A purposive sample is a sample in which the researcher selects people who are particularly knowledgeable about the topic being studied. This type of sample is less accurate than a random sample, but it can be useful in exploratory research.
In conclusion, the final result of a study will be more accurate if the sample drawn is representative to the population. This means that the sample should have the same distribution of characteristics as the population, such as age, gender, race, and ethnicity.
