A random sample is necessary to ensure that each person in the class has an equal chance of being selected. This allows for a representative sample of the larger population. Option A, multivariate sample, involves selecting participants based on multiple variables, which is not necessary for this survey. Option B, cross-sectional sample, refers to surveying participants at a single point in time, which is not relevant for this question. Option D, multistage sample, involves selecting participants through multiple stages or levels, which is not necessary for this survey.
