Sampling without replacement means that once an individual is selected and included in the sample, they cannot be selected again. This ensures that each individual in the population has an equal chance of being selected and included in the sample, and avoids the issue of duplicate observations. Therefore, B is the correct choice. A is incorrect because sampling without replacement does not guarantee independence among individuals in the sample. C and D are incorrect choices because there may be situations where sampling with replacement is more appropriate, such as when the population is large relative to the sample size.
