Explanation:

• Stratified sample: Involves dividing the population into subgroups (strata) and sampling from each. Not the case here as no strata are mentioned.
• Simple random sample: Each member of the population has an equal chance of being selected. The company randomly selects 100 customers from the database, which fits this definition.
• Cluster sample: Divides the population into clusters and randomly selects some clusters. No clustering is described.
• Convenience sample: Selects easily accessible individuals. Here, selection is random, not based on convenience.

Answer:

simple random sample
