Answer
# Brief Explanations:
In cluster sampling, the population is divided into groups (clusters), and then entire clusters are selected. The first option divides customers into groups based on cities (clusters) and selects all customers from randomly - chosen clusters. The second option is simple random sampling as customers are randomly drawn without clustering. The third option is convenience sampling as it selects easily accessible customers.
# Answer:
The analyst forms groups of 10 customers based on the cities the customers live in. Then, she selects all of the customers in 5 randomly chosen groups.
