Answer: (B)

Verified step by step guidance

1. Step 1: Identify the total number of students surveyed by summing up the frequencies for all cake flavors. Add the values: 32 (Vanilla) + 55 (Chocolate) + 34 (Marble) + 49 (Other).
2. Step 2: Calculate the proportion of students who prefer vanilla cake by dividing the frequency of vanilla cake (32) by the total number of students obtained in Step 1.
3. Step 3: Convert the proportion obtained in Step 2 into a percentage by multiplying it by 100. Use the formula: \( \text{Percentage} = \left( \frac{\text{Frequency of Vanilla}}{\text{Total Frequency}} \right) \times 100 \).
4. Step 4: Round the percentage to one decimal place if necessary, as pie chart percentages are typically rounded for clarity.
5. Step 5: Use the calculated percentage to create the pie chart segment for vanilla cake preferences, ensuring the total percentages for all flavors add up to 100%.
