Randomization is crucial in surveys to avoid bias. Bias in a survey leads to inaccurate results. An effective sampling technique aims to be unbiased and use proper random - selection methods. A representative sample, which accurately reflects the characteristics of the population, gives the most reliable and optimal results for drawing inferences.
# Answer:
C. A sample that is representative of the population produces the most optimal results.
