4

Explanation:

Step1: Convert percentage to decimal

To find 75% of 12, first convert 75% to a decimal. 75% is equal to $0.75$ (since $75\%=\frac{75}{100} = 0.75$).

Step2: Multiply by total number of slices

Multiply the decimal by the total number of pizza slices (12). So we calculate $12\times0.75$.
$12\times0.75 = 9$.

Answer:

9 (corresponding to the option "9")
