B) 40 degrees.
C) 90 degrees.
D) 225 degrees.

Adjacent columns in the visual cortex typically respond to orientations that are slightly shifted from one another. This shift is known as the "orientation tuning curve." Therefore, the column adjacent to the one that responds best to 45 degrees would likely respond best to orientations that are close to, but not exactly, 45 degrees. Option B, which is 40 degrees, is the closest answer to this.
