To determine what percentage of females polled supported Martinez, we look at the relative frequency table provided.

1. We identify the relative frequency given for females supporting Martinez, which is 0.30.

2. To convert this relative frequency into a percentage, we multiply by 100:

[tex]\( 0.30 \times 100 = 30 \)[/tex]

3. Therefore, 30% of the females polled supported Martinez.

The correct answer is A. [tex]\( 30 \% \)[/tex].
