B Correct answer
Explanation

To find the area from circumference, first find the radius. Circumference C = 2πr, so r = C/(2π) = 132/(2π) = 21 cm. Area = πr² = π(21)² = 1386 cm². Option B is correct. Options A, C, and D are calculation errors - they may have used wrong radius values or incorrect area formulas.
