CorrectNot quiteAnswer D

Correct answer: D

The areas are in the same ratio as the angles, so no need to find acres.
Wheat: 150°. Pulses: 60°. Difference: 90°.
Percentage: $\frac{90}{60} \times 100 = 150\%$ .

Worth noting

60% divides the difference by wheat's area instead of pulses' area. 40% is pulses as a percentage of wheat. 90% mistakes the 90° difference for a percentage.
