Correct answer: By about one-third.

Answer options

  1. ABy about one-fifth
  2. BBy about one-third Correct
  3. CBy about one-half

Why

On wet pavement, slow down by roughly a third: a truck that would go 45 mph on a dry road should go about 30 mph. On packed snow, cut your speed by half or more.
