To find the noon Sun angle for a latitude of 40° N on February 14, we need to look at the point on the analemma for that date and latitude.

Following the horizontal line for 40° N leads to the point at the bottom of the figure-eight loop, which represents February 14.

To find the noon Sun angle, we need to look at the vertical line passing through this point. The angle where this line intersects with the ecliptic (the curving path on the analemma) represents the Sun's altitude at noon.

The ecliptic intersects the vertical line at an angle of approximately 37°, so the answer is D) 37°.
