Answer 1

Using the information in the table, we need to add up all the R's, D's, G's and I's respectively. The results are:

`\begin{gathered} R=8 \\ D=5 \\ G=1 \\ I=6 \end{gathered}`

Then, the bar chart that represents this is the last option

Notice that the other charts have incorrect values of the frequency of G.
