Explanation:

A frequency table organizes data (both qualitative and quantitative) into classes and lists the count of observations in each class. The incorrect options describe: frequency of sound waves (not statistical frequency), a bar chart (a visual, not a table), and a relative frequency table (which uses fractions/proportions, not raw counts).

Answer:

A. A grouping of qualitative data into classes showing the number of observations in each class.
