Let's choose an angle within 30° and 40°, such as 35°. The sine of 35° is approximately 0.5736. 
When we double the angle, we get 70°, and the sine of 70° is approximately 0.9397. 
So, the sine of the angle increased, but it is less than double. 
Therefore, the answer is C, it would increase but be less than double.
