Histograms and frequency polygons are used to display data that is continuous and shows the frequency distribution of the data. In this case, the number of hours players spend practicing is a continuous variable and the researcher is interested in the frequency of players who practice at various amounts of hours. Histograms and frequency polygons are best suited for displaying this type of data.

Pie charts are used to display data that can be divided into categories and show the proportion or percentage of each category. Bar charts are also used to display categorical data but are best suited for comparing the quantities of each category. Neither of these chart types are appropriate for displaying the continuous data about hours of practice.

Therefore, choice A is the best option for displaying the data.
