To determine what percentage of females polled supported Martinez, we will examine the data in the provided relative frequency table.

From the table:
1. The total percentage of females surveyed is [tex]\(0.54\)[/tex] (54%).
2. The percentage of females who supported Martinez is [tex]\(0.30\)[/tex] (or 30%).

So, the proportion of females who supported Martinez is given directly in the table as [tex]\(0.30\)[/tex].

To express this as a percentage, we convert the decimal to a percentage by multiplying by 100:
[tex]\[ 0.30 \times 100 = 30\% \][/tex]

Therefore, the percentage of females polled who supported Martinez is:
[tex]\[ \boxed{30\%} \][/tex]

So the correct answer is:
C. [tex]\(30\%\)[/tex]
