Explanation:

1. Frequency tables organize data counts; quantitative data (like heights, test scores) can be grouped into classes and counted, so this is a valid use.
2. Classes in frequency tables must be mutually exclusive, meaning each observation belongs to only one class to avoid double-counting.
3. Qualitative data (like colors, categories) can be directly counted and displayed in a frequency table, where each category is a class.
4. Basic frequency tables show counts (frequencies), not percentages. A relative frequency table shows percentages, which is a separate type of table.

Answer:

A. They can be used for quantitative data.
B. No observation can fit into more than one class.
C. They can be used for qualitative data.
