Simple random sampling gives each element in the population an equal chance of being selected, reducing bias. Cluster sampling may have within - cluster homogeneity issues, stratified sampling requires proper stratification, systematic sampling can introduce bias if there is a pattern in the population, and convenience sampling is highly prone to bias as it is based on ease of access.

Answer:

E. Simple random sampling
