Answer
A

B
line plot
C
line graph
D
stem and leaf plot

A line plot is best for showing how often each whole-number value appears in a small set of data. Here, the number of pets ranges from 0 to 5, so the results can be marked above those values to show their frequencies. The correct choice is a line plot.
