Answer

Answer:

B. simple random sampling

Brief Explanations:

The teacher selects nine random school - days. In simple random sampling, every element in the population (all school days in the past month) has an equal chance of being selected, which is the case here. There is no fixed pattern (not systematic), no selection based on ease (not convenience), and no division into subgroups (not stratified).
