The Correct Option is D
Solution and Explanation
Step 1: Find the total Jazz responses.
Adding Jazz across all three age groups: \(1 + 4 + 11 = 16\) people picked Jazz.
Step 2: Find the total sample size.
Adding the column totals: \(33 + 33 + 68 = 134\) people took the survey in all.
Step 3: Compute the percentage.
Percentage \(= \frac{16}{134} \times 100 = 11.94\ldots\%\), which rounds to \(12\%\).
Step 4: Rule out the other options.
\(6\%\) and \(8\%\) are both too low for \(16\) out of \(134\), and \(22\%\) is roughly double the true share.
Final Answer:
The percentage is \(12\%\). \[ \boxed{12\%} \]
