a-stratified sampling
b-cluster sampling
c-convenience sampling
d-systematic sampling
e-random sampling

Answer 1

The type of sampling used is cluster sampling, where the population is divided into clusters and random clusters are selected for the survey.

Step-by-step explanation:

In this case, the market researcher randomly selected four businesses and is surveying all the employees within each selected business.
