Well, if I recall correctly, 26,000 years is the time it takes to complete a precession 'rotation' - so... It should be back to D) Summer.

The answer is summer. Precession is a 26,000 year cycle so in 26,000 years time, the vernal equinox will be back to where it is today.

summer---the precession of the axes completes in approx. 26,000 years. Presumably, barring any unforeseen effects.
