Explanation:

Step1: Calculate total number of students

Add up all the numbers in the table: $(10 + 4+5 + 12+9 + 5)=45$.

Step2: Calculate number of students who prefer vanilla

Add the numbers in the vanilla - column: $10 + 5+12 = 27$.

Step3: Calculate the percentage

Use the formula $\text{Percentage}=\frac{\text{Number of students who prefer vanilla}}{\text{Total number of students}}\times100\%$. So, $\frac{27}{45}\times100\% = 0.6\times100\%=60\%$.

A. 60%
