Pie chart is the best option to show the given data in graphical form.
<u>Explanation:</u>
We have the data of number of pets against their number of respondents and the owner wants to show the percentage of results of the survey in a graphical form.
So pie chart will be the best option here as they show categorical data which helps us to see what percentage of the whole each category constitutes.
Pie charts are best to use when you are trying to compare parts of a whole as they do not show changes over time.
