To determine the percentage of females who supported Wilson, let's take a look at the given relative frequency table:
[tex]\[
\begin{tabular}{|c|c|c|c|}
\hline
& Wilson & Martinez & Total \\
\hline
Females & 0.24 & 0.30 & 0.54 \\
\hline
Males & 0.18 & 0.28 & 0.46 \\
\hline
Total & 0.42 & 0.58 & 1.0 \\
\hline
\end{tabular}
\][/tex]
From the table, we observe that the proportion of females who supported Wilson is given as 0.24.
To convert this proportion into a percentage, we multiply by 100:
[tex]\[
0.24 \times 100 = 24
\][/tex]
So, the percentage of females polled who supported Wilson is:
[tex]\[
24 \%
\][/tex]
Thus, the correct answer is:
A. [tex]\( 24 \% \)[/tex]
