Answer 2

Answer:

B. simple random sample

Step-by-step explanation:

The company randomly selects 100 customers and asks them about their level of satisfaction with the company. Therefore, the method used here is simple random sample

A simple random method is described as a random selection of few people from a majority or a whole population. These few samples represent the whole population. Moreover in a random sampling, each person has an equal chance to participate as its random and no one knows who will be selected. Random sampling is one of the best and non biased sampling methods to conduct any survey.

The cluster sampling is wrong as this form requires groups but here the company has not grouped people. This cannot either be stratified as in stratified sampling, sub-populations are considered and here it is not considered. In convenience sampling, the closest persons are surveyed which is not the case here. So, these 3 options are wrong.

Only simple random sampling is the correct option.
