85°

To find the measure of ∠B′, we need to remember that when a figure is reflected over the y-axis, the angles in the original figure will retain the same measure while the direction of the angle will change.

In the original figure ABCD, we can see that ∠B measures 75°. Since the measure of ∠B will not change during the reflection, the measure of ∠B′ will also be 75°.

Therefore, the correct answer is 75°.
